UNMATCHED PERFORMANCE

Merino is an all-weather wonder—working overtime to help you feel your best no matter the conditions.

This magical natural fiber moves moisture away from your skin, so you stay cool when things heat up and keep warm when there’s a chill.

ALL-DAY COMFORT

BRANWYN Performance Innerwear is built to move with you—whether you’re sending your boulder problem, grounding in warrior pose, backpacking in Yosemite, or walking the dogs.

Our seamless knit technology let's you say good riddance to bras that ride up and underwear that gives the dreaded wedgie.

With our targeted women-centric construction, you may forget your wearing it—our customers often tell us they do!

EARTH FRIENDLY

Merino is a 100% natural, biodegradable, and renewable fiber.

Throughout their lifespan, sheep grow new fleece over and over, and their wool decomposes naturally in soil.

Our seamless design not only delivers that second skin comfort, it creates a more durable garment. Thanks to the strong bond between fabric layers, your innerwear maintains its shape and resists wear and tear more efficiently—reducing waste and providing more life out of each piece. Win-win.
