Built For Your Active Lifestyle

Underwear is an essential part of a daily wardrobe, and you should have the softest, comfiest fabric where it matters most. We make a variety of super soft, ultra comfortable boxers and briefs that hold up just as well climbing mountains as they do in daily life.

Nature's Fabric

In addition to being a natural, renewable and biodegradable fiber, Merino wool offers unparalleled comfort and versatility. All of our underwear feature Merino wool next to skin, and the other materials we use meet our high standards for sustainability and are used intentionally in everything we make.

(m)Force Technology

Our Merino wool underwear features our exclusive (m)Force™ Nylon Core Technology. Merino wool is next to your skin and wrapped around a continuous nylon filament to make the fabric even stronger. The result? Underwear that holds its shape, dries faster and lasts longer than 100% Merino wool at similar weights. Our (m)Force fabrics have all the technical benefits of Merino wool with the durability you normally think of with synthetics.


We let our reviews speak for themselves.

"WAY better than cotton briefs!"

John P.

Merino Wool Boxer Briefs

"Wore these during a ski trip where temperatures regularly dipped into -10s°F. They kept me warm and comfortable both on and off the slopes."

Jonathan C.

Merino Wool Boxer Briefs

"Put them through the ultimate wear test of 16 straight days in the AK back country. ... These held their shape, never loosened or drooped, zero chafe, zero 'swamp.' Stop reading and double your order right now."


Ridge Long Boxer Briefs - 9 Inch

"I’ve never owned wool boxer briefs before, but I’ve already purchased another pair after wearing them for awhile. I haven’t had any riding up and forget I have them on, which is always the goal. Highly recommend!"

Merino Wool Boxer Briefs

"I took them on a camping ultra marathon relay weekend. I love the length, finally finding boxers that come down over my quads and don't roll up. So glad I found these!"
