Good For You & The Environment

(m)Force Technology

Not sure how Merino wool underwear will hold up? Our Merino wool underwear feature our exclusive (m)Force™ Nylon Core Technology to make them more durable and long lasting than you expect from Merino wool underwear. You still have Merino wool against your skin, so you’ll be comfortable and get all the benefits of Merino wool. Our underwear fabric holds its shape, dries faster and lasts longer than 100% Merino wool at similar weights. Get all the benefits of wool plus the durability normally associated with synthetics.

Women's Underwear Reviews

Take it from our customers.

"I wear nothing else. Hiking, walking, stair master, Pilates, ALL of it they perform. 80% humidity, 100F still the best."

Heather M.

Boy Shorts Underwear

"Great cut and fit, not at all itchy. Stays put (doesn’t ride up or fall down). Highly recommend."

Christine L.

Merino Wool Thong Underwear

"So comfortable! Perfect for small chested women. Offers enough support for me. Extra warmth. Best bra I’ve ever owned!"

Kiva N.

Merino Wool Bralette

"I was surprised by how comfortable and supportive this bra is. I wanted a wool bra for all day winter sports that would dry quickly. I’m a climber, so I have bigger lats and shoulders and this bra works really well. I’ve been wearing it a lot, even for lower impact activities!"

Megan H.

Send-It Seamless Merino Sports Bra

"Really love these. They don't slip or slide and they are so comfortable - they feel like a second skin."
