Built For The Active Lifestyle

Underwear is an essential part of a daily wardrobe, and you should have the softest, comfiest fabric where it matters most. Choose from two lengths of super smooth, ultra-comfortable boxer briefs. Our boxers are made from (m)Force Technology Merino wool for increased durability and a touch of Spandex for long-lasting stretch and recovery.

Nature's Fabric

In addition to being a natural, renewable and biodegradable fiber, Merino wool offers unparalleled comfort and versatility, which makes it perfect for base layers. Merino wool regulates body temperature by releasing heat and keeping sweat off your skin. It's naturally antimicrobial, meaning it repels bacteria that causes odor and keeps you stink-free.

(m)Force™ Nylon Core Technology

Our Merino wool underwear features our exclusive (m)Force™ Nylon Core Technology. We engineered super-soft Merino wool next to skin to achieve unmatched comfort and performance, then we 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 durability typically associated with synthetics.

"WAY better than cotton briefs!"

Merino 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."

Merino Boxer Briefs

"Breathability! I have several pair for a reason. Quality and comfort! I prefer the 9 inch seams over the shorter option as the other seem to ride up a bit but not these!"

David T

Merino Long Boxer Briefs - 9 inch

"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!"
