Built For The Active Lifestyle

Underwear is an essential part of the daily wardrobe, so why not have softest, comfiest fabric where it matters most! Our Merino wool underwear is thoughtfully tailored and designed to stay in place, during the most rigorous - or relaxing - activity.

Nature's Fabric

In addition to being a natural, renewable, and biodegradable fiber, Merino wool offers unparalleled comfort and versatility resulting in the layers available. Merino wool regulates body temperature by releasing heat and keeping sweat away from your skin. It is also naturally antimicrobial, repelling bacteria that cause body odor, to stave off stink.

(m)Force™ Nylon Core Technology

Our Merino wool underwear features our exclusive (m)Force™ Nylon Core Technology. We engineered super-soft Merino next to skin to achieve unmatched comfort and performance and wrapped it around a continuous nylon filament for improved strength. The result is a fabric that holds it shape, dries faster and lasts longer than 100% Merino at similar weights. This means our (m)Force fabrics have all the technical benefits of 100% Merino wool with the enhanced durability typically associated with synthetics.

Testimonials

We let our reviews speak for themselves.

"They’re AMAZING! Perfect fit, don’t bunch up, and I love the performance of merino for long hikes. Also wore them bike packing and no chafe in the saddle!"

Robin P

Merino Boy Shorts

"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 Boxer Briefs

"Using as shorts under short skirts. Not too long, not too short. Don't ride up. True to size. So much better than polyester."

Angela L

Merino Boy Shorts

"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!"

Gaelan S

Merino 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!"
