10 Size-Inclusive Brands For Workout Innerwear

10 Size-Inclusive Brands For Workout Innerwear


From sports bras to boxer briefs in sizes XXS to 7X, these brands make the innerwear you need to thrive in any workout session

Finding the right innerwear is about more than just looking good—it’s also about hygiene. While certain brands make bottoms with built-in moisture-wicking fabric, for example, wearing underwear for the days you expect will end in a lot of sweat is still essential. This is because wearing the right underwear helps protect you from chafing, infection, and bacteria building up from moisture. Choosing the right innerwear is also essential for breathability and comfort as you exercise or play your sport.

With those reasons laid out, here’s our round-up of 10 size-inclusive activewear and lifestyle brands that provide what we think are the best undergarments to wear for exercise and sports.

1. Lorna Jane

Among the leading activewear brands for women, Lorna Jane sells a wide range of clothing and accessories for all sorts of activities. For this brand, it’s all about looking and feeling good, from your hair accessories down to your socks. In terms of innerwear, the Feel Naked Brief and Tempo Speed Ribbed Seamless Sports Bra look the most promising. Notably, Lorna Jane’s largest size is XXL while its smallest is XXS.

2. Gymshark

Likewise, Gymshark is a brand that produces a line of underwear and sports bras made precisely for their activewear, but with more style options for both men and women. For the men, we suggest checking out their Sports Tech Boxers, which run from XS to 3XL. In terms of their women’s sports bras and underwear, the Adapt Fleck Seamless Sports Bra, Sweat Seamless Longline Sports Bra, and Seamless Boxers can be what you need. These three items are available in XS up to XXL.

3. Under Armour

On the other hand, Under Armour is a brand well-known for its innerwear as much as its apparel due to the quality and longevity of its products. If you weren’t already familiar with it, then we suggest starting off with the Men’s Charged Cotton® 3″ Boxerjock® or Men’s UA Tech™ Mesh 6″ Boxerjock® first, both of which come in a size range of XS to XXL. Meanwhile, Under Armour has XS to XL seamless and stretchy women’s underwear in two types: thong and hipster. Of that selection, the UA Infinity High Zip Sports Bra looks the most promising, and it comes in XS up to XXL.


SEFI plus size innerwear

SEFI doesn’t provide as many size options for bigger women, but we would be remiss not to mention SEFI on this list for their high-quality sports bras, which all sport fun designs and breathable, antibacterial, and moisture-wicking features. Coming in at XXS up to XL, the Move With Me Square Bra and the Silhouette High Neck Bra could suit petite and midsize bodies best. Additionally, while panties made for exercise and sports aren’t provided at SEFI as of yet, the brand does also produce lingerie, but in limited sizes and designs.

5. Athleta

Popular size-inclusive activewear brand Athleta also has a line of women’s innerwear to choose from. For sports bras, you can look into the Exhale Bra in colors like Salvia Pink and Conscious Crop Bra in colors like Orchid Pink for studio classes, such as yoga and pilates. Notably, Athleta’s apparel comes in a size range of XXS up to 3X. In addition, Athleta’s underwear collection is made specifically for lounging, relaxing, and sleeping. Though not suitable for intense exercises and activities, their underwear is still breathable and quick-drying, so they can be worn for low-impact exercises.

6. Girlfriend Collective

Another great brand to try out is Girlfriend Collective, which makes ethically-made clothing in sizes XXS up to 6XL. Here, you can pick out the Bree One Shoulder Bra, Stevie Shirred Ballet Bra, or Emerald Sofia Strappy Back Bra for your next gym session or jog. Girlfriend Collective also makes high-quality sports briefs and sports thongs, which you can buy in packs or in single pieces.

7. Lululemon

Lululemon also has a fairly size-inclusive wide-range selection of innerwear to choose from for both men and women. For men’s underwear, you can buy pieces that are designed precisely for everyday comfort or training, with other factors to consider such as fit, fabric, and length. Here, it’s worth checking out the Rapid Vent Tech Boxer, which is seamless, lightweight, and built for training. For women, you can look into the UnderEase Super-High-Rise Shortie Underwear and Enlite Front-Zip Bra for support. 

8. Superfit Hero

For more size inclusion, Superfit Hero is the premium activewear brand to watch out for. Sports bras here go from Large to 7X as they were designed precisely for the women typically left out of conversations regarding fitness and wellness. In terms of top picks, you can start off with the Superhold Sports Bra as this highly-reviewed product reportedly provides supreme comfort and support.

9. Adidas

Adidas should also be your go-to brand for men’s innerwear for training. The workout boxer briefs many men recommend are the black Performance Boxer Briefs, which come in a size range of Small up to 2XL. These workout briefs are seamless, comfortable, quick-drying, and comfortable, making them perfect for the gym. For women’s sports bras, you have many high, medium, and light support options, such as the TLRD Move Training High-Support Bra, CoreFlow Studio Medium-Support Yoga Wind Bra, and Light-Support Flower-Print Bra.

10. Uniqlo

Last but not least, we highly recommend Uniqlo for its AIRism Innerwear collection, which includes a wide array of undershirts, boxer briefs, bras, camisoles, and much more. Here, we recommend the AIRism Ultra Seamless Shorts and AIRism Bra Sleeveless Top for women. Meanwhile, the AIRism Boxer Briefs and AIRism Anti Odor Mesh Tank Top for men look promising. Notably, the first two products come in sizes Small up to Extra Large, while the latter two go up to 3XL.
