UNMATCHED PERFORMANCE

Merino wool empowers you to stay cool, comfy, and dry, all day, every day.

This magical material can hold up to 30% of its weight in moisture without feeling wet, so you keep comfortable regardless of how sweaty things get.

Natural thermoregulation means you stay cool when it’s hot and warm when it’s cool — aka always comfortable.

ALL-DAY COMFORT

Whether you’re balancing in warrior pose, going full send on a new climbing route, running a 10K, backpacking through Joshua Tree, or walking the dog, our Innerwear is built to move with you.

Seamless knitting technology means no digging, while women-centric construction stays put without riding up, slipping down, or giving you a wedgie.

Our customers say they forget they’re even wearing it.

EARTH FRIENDLY

Merino is a 100% natural, biodegradable, and renewable fiber.

Sheep produce new fleece over and over, and their wool decomposes naturally in soil.

Compare that with polyester, which takes 500-plus years to decompose.

Plus, we use only ZQ-certified wool, which guarantees ethical treatment of our beloved sheep.
