Why Merino Wool?

In addition to being a natural, renewable and biodegradable fiber, Merino wool offers unparalleled comfort and versatility resulting in the best base layers you can get.

Merino wool regulates body temperature by releasing heat and wicking sweat away from your skin. It's also naturally antimicrobial, repelling bacteria that cause body odor to stave off stink.

(m)Force™ Technology

Our Aspect Merino Wool Base Layers feature our exclusive (m)Force™ Nylon Core Technology. We engineered super-soft Merino wool next to skin to get 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 wool at similar weights. This means our (m)Force fabrics have all the technical benefits of 100% Merino wool pieces with the enhanced durability typically associated with synthetics.

Go Farther, Stay Out Longer

Whether you're skiing with our Aspect base layers, working out in the Convict Canyon Joggers (pictured) or sitting around a campfire in the Hyde Joggers, you're going to stay comfortable thanks to all the benefits of Merino wool. You'll forget about what you're wearing so you can focus on whatever you're doing.

Men's Pant Reviews

Take it from our customers.

"Great heavyweight jogger, or super cold day base layer. Love them!"

Nicholas B.

Convict Canyon Jogger

"I've now amassed a complete collection of Aspect bottoms and Zip tops (black, gray, navy, green/camo) and couldn't be more satisfied...I basically live in these bad-boys December through March."

Frank R.

Aspect Midweight Base Layer Bottom

"I love these joggers/sweatpants. So soft and no matter the climate you are always regulated, whether cool or warm. The best investment I ever made recently has been changing all my clothes to sustainable wear."

Rafael L.

100% Merino Hyde Jogger

"Supremely comfortable baselayer."

Jesse L.

Inversion Heavyweight Base Layer Bottom

"These are the perfect length so they don't get bunched up in ski boots. Warm, wick well and comfy."

Ryan R.

Aspect Midweight 3/4 Length Base Layer Bottom

"I'm a bit over 2 weeks into owning these, and despite working to reduce the number of pants I have (one of my reasons for buying these), I've come close to buying a second pair."
