Merino Performance Innerwear

In: Apparel >

Performance Innerwear lets you focus on your goals instead of your gear. Crafted out of natural fibers from Merino sheep, our fabric tames boob sweat, banishes sogginess, and eliminates funk.

All of our bras and bottoms are super-soft to the touch, stretch to move with you, and help your body breathe, stay dry, and maintain the right temperature.

From the mountains to the yoga studio and every adventure in between, Performance Innerwear will keep you supported and comfortable.

BRANWYN was founded with the simple idea to support women always, in all ways. We know that high-performance underwear makes it easier to achieve athletic dreams—and conquering our goals powers our ambition so we can build a better future for ourselves, each other, and Mother Earth.

Our designer Shawna set out to find a pair of underwear made from natural fibers that she would actually want to wear while exercising.

But as she searched, Shawna realized that her perfect pair might not exist.

The only options she could find were bad-for-the-planet polyester-cotton options that would get soggy in no time flat, or styles that just weren’t cut in a way that allowed a woman’s body to move.

It took two years of research and development and countless prototypes before she and her technical designer (who moonlights as her mom!) struck gold in a seamless blend of Merino wool, nylon, and elastane.
