Koichi Tsukamoto founded Wacoal in 1949, in Japan. He was passionate about bringing to the market gorgeous intimate apparel that offers more innovation and higher quality than other products available. He began by building teams made up of like-minded researchers, designers, merchants, etc, and created his brand, Wacoal, that ended up reaching a worldwide audience due to a large number of loyal customers. Wacoal came to America in 1985, delivering its high-quality, comfortable, and beautiful intimate apparel for more to enjoy.

Koichi’s mission was to help women feel and look beautiful in their own skin. The company understands that it can literally be life-altering when you finally find a bra that fits right, provides enough support and is comfortable. For this reason, the bras are offered in a wide variety of sizes and styles. They are made for cup sizes A-I.

The design team works hard to keep its products trendy without compromising on what matters most: comfort and quality. The dedication to quality has granted Wacoal a good reputation and a loyal fanbase.

Wacoal is so committed to helping women find the right fit that they have a group of trained consultants available to accurately measure you and choose the style that will work best for your lifestyle and body type. For other intimate products, check here.


The Wacoal Underwire Sports Bra is made with a blend of nylon and spandex. Eighty percent of the construction is nylon, with the other twenty percent being spandex. The back of the bra is mesh (nylon) in order to create better airflow. Together, the materials are going to work to bring stability, support, stretch, durability, and comfort.

Nylon is a very durable, man-made material that brings your bra strength. It will keep your bra from bursting or tearing and even protect it from some chemicals. It gives the Wacoal Underwire Sports Bra great air permeability, wicks away moisture, and dries quickly. This is great news for girls with large busts, active women, and those who live in hot climates.

Nylon is a man-made material, and it is very durable. Nylon is what gives the bra a strength. It will protect your bra from tearing and bursting. It will even protect it from certain chemicals. Nylon has good air permeability and dries quickly. If you’re active, live in hot climates, or have large breasts, you’ll appreciate that in the Champion Underwire Sports Bra. It is important to note that if you have sensitive skin you could become irritated by the chemicals in nylon material.

The Wacoal Underwire Sports Bra wouldn’t be what it is without the spandex that’s included in its’ construction. Spandex comes with a lot of benefits. It provides support, durability, flexibility, and shape retention. It allows you to have a more secure, proper fit; longer. Your bra won’t lose its shape and become worn-out as quickly, thanks to the spandex. For other apparel made with spandex, check here.


When breasts don’t have the proper support, especially for high-impact activities, it can result in a lot of unnecessary and unpleasant pain and discomfort. Even though your breasts don’t have muscles, the skin and ligaments still experience strain and stretching when they move with your body. And let’s face it if you’re exercising, and you’re large-breasted, they’re going to be moving; a lot.

That’s why Wacoal Underwire Sports Bra works so hard to bring you the support you need. It is designed specifically for full-busted and/or full-figured women in order to provide maximum support. The cups are double-layered and include an underwired frame that is on the outside of the cups, which will help to better reduce the motion.

There is also an inner sling in the Wacoal Underwire Sports Bra. This is a support feature that has strips of fabric following your natural curve, like the underwire, but they are softer and are built right into the cup. This helps you get an extra layer of support without adding a bunch of bulk.

The Wacoal Underwire Sports Bra has a hook and eye closure, which means that it will bring you more support than a pullover bra would. Adjust it to the perfect tensile strength for you and enjoy the support it brings you. If you want to get creative, you could use this to help with support as well.


It is harder and harder to find clothing that fits right. Even harder for those who have bigger breasts and chests and bodies. Wacoal is aware of this problem and works hard to cater to as many women as possible. The Wacoal Underwire Sports Bra is made for women who wear bras with a cup size between C and H. For those with cup sizes G and H, an inner sling is included for additional support. Consumers have reported that this bra does run small, so considering ordering a size up.

The Wacoal Underwire Sports Bra is designed for certain breast shapes, as well. The breast shapes it is best for include: shallow top/full bottom, round, east/west, and pendulous. If you need to look at another bra for larger breasts, check here.


Breathability is especially important in clothing, especially bras. And those with big busts will be able to confirm that it is exceptionally important to them. Even if you don’t participate in extremely high-impact activities, you will probably still deal with a little bit of sweat, right?

The Wacoal Underwire Sports Bra works hard to keep you cool, dry, and comfortable. The nylon material that makes up the majority of the bra will give you breathability. It has the ability to wick away moisture from your skin to keep it dry. It also has the ability to dry quickly once it’s absorbed the moisture, which will keep your skin cooler. The back of the Wacoal Underwire Sports Bra is even meshed, allowing more air to flow freely. For other breathable products, check here.


A lot of women have resorted to accepting that they have to sacrifice either style or functionality when it comes to bras. Typically, the pretty ones are either outrageously priced or don’t provide enough support to be worth the pretty patterns. However, the Wacoal Underwire Sports Bra doesn’t make you sacrifice on anything.

The design team successfully kept the bra shape flattering while providing optimal support. Your busts will keep their shape, your straps will stay on your shoulders, and not so close to your neck that they show through even your t-shirts. Since it is a hook and eye closure, instead of a pullover, it will be a lot easier to put on and take off. If you need a pullover bra, check here.

The Wacoal Underwire Sports Bra is designed to be used for high-impact activities. These could include tennis, basketball, volleyball, running, etc. For more workout sports bras, check here.

The Wacoal Underwire Sports Bra is available in black, lilac grey/Caribbean sea, surf the web, naturally nude, pastel lilac/midnight blue, hollyhock/violet indigo, violet indigo, platinum/fuschia, royal blue/grey, indigo bunting/navy peony, dazzling blue/grey, Carnivale red, Haute berry/deep ultramarine, blue iris, peacoat/jade lime, Poseidon/Caribbean sea, purple opulence/yellow, dazzling blue/grey, sand, teaberry/grey, and white.


Even though it’s extremely important to have a snug, supportive fit in your bra, it’s just as important to have flexibility. Your whole body moves when you do, including (especially) your breasts. Yes, it’s good to keep them from bouncing everywhere, but they need to be able to move with your body, too.

The Wacoal Underwire Sports Bra may be rated for high-support, but it also offers a fair amount of stretch and flexibility thanks to the spandex that is integrated into the construction. The spandex will give you enough wiggle room to move comfortably while still receiving the support you need.

The spandex will help prolong the life of your bra as well. It will work to help it retain its shape, even after months of workouts. The mesh backing will also allow more flexibility. If you’re looking for more apparel with stretch, try here.


Something that is very important, and sorely lacking most of the time in sports bras, is room for adjustments and customization. Some sports bras are made to be pulled over the head and have no options for adjustment, in either the straps or the band.

The Wacoal has options for adjustments in both the straps and the band. Straps digging in? Loosen them. Breasts sagging? Tighten them. The band being adjustable is helpful because not everyone with the same cup size has the same chest size. Find your perfect fit and support level. For another adjustable option, try here.


The Wacoal Underwire Sports Bra provides the perfect amount of coverage for the active, large-busted woman. It does not dip down low in the front. This will provide you with more support, more comfort, and more coverage. You can even wear it as a camisole under a v-neck top.

The band does not become unreasonably narrow as it wraps around your ribs to your back. This will help control any spillage you’d typically get from a bra with a more narrow band. For another option with a wider band, try here.


It’s important to know whether or not you have the option to return your items, especially when you’re purchasing clothing items online. It’s nearly impossible to know your correct size unless you’ve ordered from the company before. Thankfully, the Wacoal Underwire Sports Bra comes with a satisfaction guarantee.

Wacoal doesn’t offer exchanges at this time. However, you can simply return your item and then place an order for a replacement item. For a full refund, make sure that you keep your tags attached to the garment. Try the garment on over top of clean clothing instead of your bare skin.
