Pros:

Merino wool

Comfortable fit

Fun colors

Cons:

Wide crew neck

A little itchy

What we liked most about this base layer top from MERIWOOL is that it is going to be something that will be perfect to wear in both cooler and warmer climates. The use of this type of wool is the perfect material that is going to help keep sweat away from your skin but still keeps you comfortable in all types of climates. This means it is going to be something that is perfect for those early morning runs when the morning is crisp but the afternoon is a little balmy.

The fit of this base layer is what makes it stand out from the rest. It doesn’t offer that same compression type of style that feels like you are going scuba diving. The fit of this design looks more like a casual shirt that you would wear for a day of running errands, but the materials are going to help regulate your body temperature.

It is offered in colors that include neutral dark and light colors such as black, charcoal, and gray, but also army green and a very light gray option. The wide variety of sizing options are going to allow you to get the perfect size for you, and from what we have found is that many users feel that this design fits them exactly as they expected it to fit.

For those that are looking for something that has a more casual fit that is going to be something perfect for those long distance runs that take up an entire afternoon or for just a fun day out running errands- this design is going to be a great and comfortable choice.

Pros:

High-quality materials

Cons:

Very long sleeves

Itchy seams

This base layer from ColdPruf is a great option if you want something that is made from materials that are really going to help regulate your body temperature, but it is also incredibly stylish so that you can feel good about wearing it on its own when you start to get a little too hot.

Read more

The materials that are used to make this design include a blend of polyester and merino wool. Polyester is going to make it a little more stretchy and soft, and the 30 percent merino will is going to help wick away moisture and sweat that will help keep you from overheating.

There are a lot of sizes that you can select from, ranging from small and running all the way up to 3XL Tall. Plus, about 84 percent of past users felt that this design fit them exactly as they expected it to fit. Color options are a little bit more limited, and they include black and a very light gray.

For users that want something that is going to be a little bit easier to take care of and take a beating, this design that uses a blend of merino wool instead of 100 percent wool is going to be one of your better options.

Pros:

Loose fit

Flat-locked seams

Cons:

Unclear sizing chart

Shorter sleeves

Sometimes, these types of clothing can be a little bit on the tight side. If you are someone that likes all of their clothing to fit just a little bit loosely, this will be the best base layer for you. We liked that it is made to fit well, and it also comes in a variety of colors so that you can take to the trails in style!

Read more

The first thing that we noticed about this design is that it fits loosely on the arms as well as the torso, and it has a crew neck that is going to be easy to pull on and off, and it won't strangle you even if you have a thicker neck. Plus, you won't have to worry about itchy steam lines because all of the seams of this design are flat locked.

Sizing is just a little bit more limited with this option than with other designs that we have seen out there on the market. Sizes start at small and run up to 2XL with no cuts for those that are taller. However, if you fit into one of those sizing options, there is a very good chance that it is going to fit just as you like it. About 85 percent of previous users found it fit them exactly as they expected it would.

If you don't like the idea of a bottom shirt that feels tight and constricting like you are about to go scuba diving, this design is going to be a great choice that is going to keep you dry and comfortable.

Pros:

Trusted brand

Lightweight

Easy to wash

Cons:

Very tight

You might already have a piece of Under Armour gear already in your closet, but it never hurts to add just one more! What we love about this brand is that they always use high-quality materials for their products which means they are are going to hold up well through multiple washes, and also provide you a good deal of protection and comfort.

Read more

This thinner option of this base layer is composed of a blend of 92 percent polyester and 8 percent elastane. The polyester is going to work to wick away sweat and moisture so that it doesn't settle on your skin and make you cold, and the elastane is going to help give you that second skin feeling with minimal shifting.

Sizing options of these base layer tops are a little more generous than other designs and include sizes that start at small and run up to 3XL. The elastane found in this fabric is going to help provide a more skin tight feel, so even if you are a little unsure about what size you are, there isn't going to be a big chance that you won't be able to slip this up over your head even.

For big fans of the Under Armour brand, this is another excellent option to add to your closet. It is composed of their special UA Base 4.0 materials that are going to really help keep your body heat from escaping on those cold mornings.

Cons:

Limited wind resistance

Helly Hansen is a brand that grew in popularity making gear for those that work in the most extreme conditions: professional fishermen. When working on the ocean, you want something that is going to be lightweight so that you can move freely but also prohibit you from losing precious body heat. Helly Hansen brings all of those features to this base layer so that no matter if you are sailing the high seas, or trail running on a brisk fall morning- you are going to stay comfortable. If you like to train in super cold climates- this is going to be one of your best options!

Read more

Unlike some of the polyester blends that we have seen, this option is a lot thicker. It is made from a merino wool exterior with lifa fiber technology to give you that snug fit. If you are out in really cold climates and want to stay warm- this is going to be one of your best options. Due to the fact that it is just a little thicker than most means that you are going to be able to feel the weight of this option under all of your clothes.

Like all Helly Hansen products, sizes are made to fit just about anyone. Sizes start at extra small and run all the way up to 4XL! Plus, they provide users with a very detailed sizing chart so that you can ensure you get the right fit for your the first time. From what we discovered- this sizing chart is pretty accurate with about 3 out of every 4 users finding that this fit them just as they expected.

For those that want something that is made for some really harsh temperatures that are going to work around the clock to keep you warm no matter where your travels may take you, this merino wool base layer is going to be an excellent choice!

Pros:

100 percent merino

Hemmed seams

Cons:

Very thin

Runs short

For some users, merino wool is the absolute best material because it's incredibly lightweight, soft, and effective at wicking away moisture. The good news when it comes to this base layer from LAPASA is that it is made from 100 percent merino wool so you know it's going to do a great job on those very cold nights.

Read more

As we mentioned above, this design is made from 100 percent merino wool. While this is going to be great for keeping you comfortable and dry, it also means that there are no stretchy fabrics that are going to act like a second skin. It does, however, utilize a rib knit fabric that is going to offer you a little bit more stretch than normal.

A crew neckline that runs just a little bit wide means that even if you have a thicker neck, you aren't going to be strangled by this men's base layer top when you pull it on. Plus, all of the seams offer similar hemming throughout the garment so you won't have to contend with loose seams that can sometimes be itchy.

For those that are looking for something that is made from premium materials that also offer a great construction that is going to keep you just as comfortable as you are warm and dry, this design from LAPASA is a great choice.

Cons:

SmartWool is a company that was founded by 2 ski instructors, so they know a thing or two about staying comfortable in harsh climates! As of 2011, they were acquired by Timberland, which is a company that is known for its high quality and well-crafted products. This design is going to offer the user a shirt that is made from high-quality materials that will keep you dry and comfortable, no matter what the weather!

Read more

What we liked most about this base layer is that it is crafted from merino wool, which is going to be a perfect material that will help to wick away sweat from your body as you begin to heat up. Plus, the short sleeves are going to help promote a full range of motion when you are working with multiple shirts and jackets.

If you love bright and fun colors, you are going to really like this option. It is offered in far more color choices than many of the other designs that we have seen out there on the market. As far as sizing is concerned, an impressive 85 percent of previous users felt that this option fit them exactly as they expected.

For those that want something that is going to be a little less restricting and will allow them to strip down to a lightweight and breathable top as the weather starts to warm up, this is going to be one of your better options.

Merino wool

Many colors

Cons:

Narrow torso

What we loved most about this design from Merino 365 is that it marries style and function to create a piece of clothing that you will be enthusiastic to slip on before heading into the elements. This company is passionate about using high-quality merino wool that is known to be one of the better materials for outdoor gear.

Read more

One of the very first things that we noticed about this top was that it has thumb loops at the end of the sleeves. Not only do these thumb loops add just a little bit of style to this top, but it also allows you to add more shirts and jackets without that terrible feeling of a sleeve that bunches up at the elbows. If you want something that is functional and stylish, this is a great choice.

Concerning the materials used, it's hard to find anything better than merino wool. This material is lightweight and is going to feel comfortable against your skin, but it is also going to work wonderfully at wicking sweat away from your skin so even as you begin to sweat, your skin will stay high and dry!

Users really love the addition of the thumb loops on the sleeves, which makes this style worth checking out. It is stylish enough to be worn on its own for a day of simple errands, but the materials used are a great companion to long, cold days out on the trails.

Cons:

If you have ever purchased a Nike product, you know that it is something crafted with active people in mind. What we liked most about this men's base layer top is that it sports a classic design that is going to help keep you comfortable on the trails, and it is made from durable materials that will be able to stand up to quite a few trips through the washing machine.

Read more

This design is made from a blend of polyester and spandex. The spandex will give you a good stretch so that it stays firmly in place to feel like a second skin, and the polyester will help wick away moisture when things start to get a little sweaty.

From our research, we have found that about 73 percent of users felt that this design fits them as expected. This number is a little bit lower than some of the higher designs on our list, but it is still a pretty impressive number. The good news here is that there are a ton of various size options to select from, and they include short and tall options for all of the various sizes.

When it comes to Nike, you know that you are going to get good quality. You may have to be a little more careful to ensure that you get the right size for your body type, and once you find the right size this is going to be a stellar choice to wear whether you prefer to walk or run on those cool mornings.

Most of the designs that we have considered have long sleeves, which is going to be ideal for all types of climates. What we liked about selected a sleeveless option is that you are going to have a lot more control of what you are wearing when out on the trails.

Read more

The blend of polyester and spandex is the key to keeping sweat that develops away from your skin. If you are running in an area that is incredibly cold in the morning but really heats up when the sun comes out- this is going to be an excellent design that is going to keep you nice and comfortable. Plus, this base layer tank top comes in a lot of different color options to match your personal style.

Sizing for this base layer tank top is going to be a bit of a problem. About 69 percent of previous users feel that this design fit them as expected. It is only offered in sizes that start at extra small and run all the way up to extra large, and the sizing chart provided only measures a users chest.

What makes this design worth a look is the quality of materials used, the flat-lock seams that will eliminate that annoying itchy feeling, and the sleeveless design that will make it a perfect option for when the sun starts beating down.

Criteria Used for Evaluation

Materials

Hands down, the materials that a garment is made from was the very first thing that we considered.

The thing that makes one of these products effective isn't because they fit really tight to your skin, but rather that they are made from materials that are going to help wick away sweat and moisture from your skin. When you are running and you really start to build a sweat, the materials used are your first line of defense to keep you dry. We have broken down the various materials that we wanted to make sure that were included in each design and the pros and cons of using each type of material.

Merino wool: As always, merino wool is one of the best materials to use in this instance. It is incredibly lightweight and soft and may not even feel like the material of your standard workout gear. However, what makes this material special is that it has a built-in UV resistance, and it is a powerhouse at wicking sweat away from your body. The only downside to this type of material is that it doesn't wash as well as your standard polyester. When washed frequently (as you should!) the materials are going to lose their shape a bit, especially more than polyester.

Polyester: Ah yes, tried and true polyester. This material may not have the same super soft feel as merino wool, but it is one very strong material. We liked to opt for designs made from polyester because this is a great material that will wick away sweat from your body and it is built like a tank. You can throw this type of material into the washing machine once a day for years and it isn't going to lose its shape or durability the way some of the other fabrics will. Users sometimes shy away from polyester because it has gained an unfair bad rap over the years, but we think that it is one of the best materials to use for workout gear that gets a tad gross and sweaty!

Spandex: What would a piece of workout gear be if it didn't have just a little spandex? That's exactly what we looked for in these garments- just a little bit of spandex. This material is going to give you an excellent range of motion that will be necessary when you are engaging in activities such as plyometrics or HIIT training. Designs that used between 5-10 percent spandex in their designs were ideal. This material is going to give you that second skin feeling, and it allows for just a little bit of extra wiggle room when it comes to picking out the right size. Just make sure that you don't select an option that has too much spandex because it is a material that won't really allow your skin to breathe.

Size

There is nothing worse than an ill-fitted tight top, and we wanted to make sure that we selected designs that would spare you from that unfortunate occurrence.

You want to make sure that it is going to fit a little snug against your skin without feeling like you are inside of a sausage casing. If you are running to shed those extra winter pounds, the fit is something that is going to be even more important! There were a few things that we considered to make sure that you found the perfect size for your body right out of the gate.

Sizing charts: When shopping for clothes online, it can be a little unnerving to purchase something that you weren't able to try on first. A good, detailed sizing chart is going to be your best friend in this instance. We liked companies that provided sizing charts that will not only give you the suggested size for your chest but also an idea for the neckline and arms as well.

Size options: We tried to shy away from companies that only offer sizes in the small, medium, and large categories. Runners come in all shapes and sizes, and we want to make sure that we include everyone! One thing that we noticed some companies included were options for those that are short or tall. There is nothing worse than finding a top that barely touches the top of your workout pants, or something that is so long that it comes down to your knees. If you are a little on the short side (or tall size) companies such as Nike offer designs that are made just for you.

Users reviews: We always look at users reviews to get a general idea of the quality of the product, but we made sure to pay extra special attention to what they were saying about the fit. Users are going to be the very first to tell you if something runs a little large, or if they have unreliable sizing that doesn't quite match up with their recommended sizing chart. If our experience, if there are quite a few users that say a certain design runs a little small, that it almost always the case!

Fit

When we talk about fit, we are also talking about the specific cut of the garment.

Certain cuts in the fabric on the cuffs, sleeves and the neckline are going to give you an indication of how well and how snug a garment is going to be. When looking at proper fits that will match everyone's needs, there were a few things that we considered when selecting our styles.

Neckline: No one likes something that is going to feel like it is strangling them around their neck, so in this instance, a crew neckline is going to be one of your best options! The majority of the products that we selected for our list offered a crew neckline because we found that is the style that most users wanted most. A crew neck is going to give you enough room to breathe, but it is also going to ride up high enough so that you don't lose any heat around your chest and collar bone. Plus, crew necks are wide enough that it is going to be simple to slip up and over your head.

Cuffs: When we looked at the sleeves on these designs, there were a few things that we considered. A good, thick hem that sports some extra elastic or spandex is going to help keep long sleeves in place as you add more and warmer clothing and jackets on top. There is nothing worse than bunched up fabric in the elbows and around the shoulders as you pile on additional gear, which is why tight fitting cuffs are going to be your first line of defense against bunched up fabric. The Merino 365 design even went a step further of offered users thumb holes in the sleeves to really make sure that those sleeves stay put no matter how much you move.

Style

It may start off as something that goes unseen at the beginning to the day, but as you work up a sweat it may be the only thing that you are wearing as you finish up your workout.

When it comes to clothing, style is always going to be something that we consider. Sure, your primary need when it comes to workout gear is that it is going to be functional, but there is no reason that you cannot look good while getting in shape! We liked brands that married function and style together so that you are always looking great.

Color options were one of the first things that we looked at when considering a certain style. We were big fans of brands that offered users a wide range of color options that spanned the darker, neutral tones such as black and gray, and ended with lighter colors such as yellow and white. It is important to also consider the color depending upon the weather. Darker colors such as black are going to absorb the sun's rays and make you hotter than a lighter color option.

The cut of the material is something else that we considered. While long sleeve designs seem to be the choice for most athletes, we also wanted to select a few options that would allow users to bare a bit more skin when the temperatures start to rise. That's why we made sure to include a few designs that offered short sleeves or even no sleeves at all. Designs such as these may not work as well as regulating body heat (especially in your limbs) but they are going to help give you a larger range of motion and feel just slightly less constructing than their full-length counterparts.

Comfort

While we don't have the science to back us up on this claim, we strongly feel that the more comfortable you are when running, the further you will be able to push yourself.

The biggest pitfall that users run into when selecting a good base layer is that it fits too tightly. No one feels good when they are wrapped up in a sausage casing and it is really going to hinder your full range of motion. However, when designs are built a little too loosely, they are going to bunch up in all the wrong places and they won't be able to do their job at wicking away moisture quite as well. So, what are the things to look out for to ensure that it is comfortable?

Seam lines: The materials used are going to play a big part in what keeps you comfortable. One of the biggest features that we noticed users really loved was flat-locked seams. Look down at the shirt that you are wearing right now, and flip it to the underside to check out the seams. You are probably looking at a seam that sticks out like a tab, right? For casual cotton and loosely fitting clothing, this is perfectly fine. However, these seam lines can be incredibly itchy and uncomfortable when worn so close against your skin. Flat-lock seams are sewn down into the fabric so that they won't stick out and drive you crazy!

Sizing: It is super important that you select the right size! You may be someone that generally buys your clothes just a little too big or a little too small because you like the way that it fits, but you simply cannot do that in this case. A shirt that is too small is going to roll up on you as you workout, and it is also going to greatly restrict your range of motion. Designs that are too loose aren't going to be able to do their job quite as well, and often bunch up in the worst places when you pile more gear on top.

Merino Wool

Merino wool is a very special type of material! It is so special, in fact, that shipping it outside of its native region of Spain in the 17th century was consider to be a very serious crime!

What's my size?

When determining the size for a basic shirt, manufacturers take into consideration not only the width of the waist, but also the circumference of the neck and arms as well.

Name that Shirt!

The classic buttonless and collarless shirt that we have all come to know and love is actually a pretty recent invention and began to really gain popularity in the early 1900s.

Other Factors to Consider

Bottom Line

The human body is equipped with tools that will help you keep your body temperature regulated when you start to get a little too warm, but these sweaty functions don't take into consideration the fact that you are wearing clothing. Sure, if we were all able to get in a good workout in our birthday suit we may not run into these type of problems such as damp clothing, but there are many laws in place preventing us to do so!

Plus, if running is something that you are still fairly new at and you are shopping around for the perfect gear to get the most out of your training, these products are going to be something that you are going to be reaching for all year round!

A good base layer to build from when you are gearing up to head out in the elements is not only going to help wick away sweat from your skin to keep you dry, but it is also going to allow you just a few more clothing options that you can transition into once your trail running really starts to pick up speed! Just be sure that your journey to wick away sweat doesn't just end with the upper part of your body, there are other places runners sweat that can lead to problems as well.

Frequently Asked Questions

q: Why do I need to wear a base layer?

a:

Sweat is your body's way of cooling itself when you start to get a little hot when engaging in activities such as running. This feature is incredibly handy when running naked, but running naked is kind of against the law.

While sweating is a great thing to regulate your body temperature, that sweat is going to wind up soaked into your clothes- and that can be a real problem. Sweaty clothes are incredibly uncomfortable in the summertime and can lead to chafing and sometimes even heat rash. When you are going for a jog in really hot weather, sweaty clothes can be your worst enemy! In cooler climates, it can be even worse, because it will seep into your clothing and actually make you even colder!

That's why equipping yourself with moisture-wicking clothing is going to be your key to staying comfortable, no matter what the weather conditions are. Whether you are just out for a quick jog on your lunch break, or you are heading out for a weekend of camping, having a good quality base layer under your clothes is going to be the key to actually being a happy camper!

q: Is it something only to be worn in colder climates?

a:

Sure, the name implies that it is something that you wear under a few layers of clothing when heading out into colder climates, but it is actually something that you may want to consider even in the warmer months.

This thin layer of material isn't actually designed to keep you warm. It is designed to keep moisture away from your skin that could make you cold. In warmer climates, keeping moisture away from your skin is actually going to act as a cooling mechanism, because it is going to allow your skin to breathe.

q: Why choose merino wool base layer?

a:

We love merino wool! This material can be the absolute best option when you want to feel light and mobile, but it also offers a myriad of benefits that you might not even be aware of.

Did you know that this material has natural UV protection built right into the fabric? This isn't something that manufacturers have added after the fact- the sheep that rock this wool never get sunburned because their wool naturally repels those harmful UV rays. That means that when you wear a garment made from merino wool, you won't have to worry about UV rays seeping through your clothing.

Merino wool has an almost hair-like quality in its natural form, which means that it is going to be incredibly soft and lightweight. When you hear the word 'wool' you may conjure images of uncomfortable Christmas sweaters, but this type of wool doesn't even compare.

q: Can I toss it into the washing machine?

a:

Since it is something that is going to be face to face with all of your sweat, washing it is going to be an important feature. The good news here is that if it is made from merino wool or polyester, you can simply toss it into the washing machine. We recommend that you give it a good wash after every run, or you may quickly find that all of your friends are 'busy' every time you suggest going for a run together.

We do suggest, however, that you skip the dryer when washing your garment. Many designs may say that they are suitable for the dryer, but these fabrics may lose shape or durability when frequently subjected to high temperatures that come from the dryer.

q: How tight should it fit?

a:

Ideally, they should feel like a second skin. This means that they should fit pretty tightly, but not so tight that they are going to roll up as you run or cut off circulation to your limbs. In fact, designs that fit just a tad loose are still going to help wick away moisture, but they just may not feel as great when worn under your clothing.

Imagine what it feels like when you wear a baggy t-shirt under a button down shirt. You may notice that it starts to bunch in certain areas as you make your way throughout your day, and after a while, it starts to feel awkward and uncomfortable. Sure, a loose fitting shirt may feel good and natural when worn on its own, but you have to take into consideration how it is going to move when you add a sweatshirt or a jacket over top.

q: Can it be worn for things other than running?

a:

Absolutely! In fact, the Helly Hansen design on our list was originally made to help keep professional fishermen warm while working on the high seas. This is going to be the perfect thing to wear whenever you are in a situation where you want to keep your body temperature regulated.

Camping is one of the best uses of this product. No matter what time of year that it is, the nights and mornings are bound to be a little on the chilly side, and the afternoons are typically much warmer. By popping on a good moisture-wicking base layer before you get dressed in the morning will ensure that your body temperature is going to be even no matter how cool the night gets, or how hot you get while hiking to the top of a mountain.
