Mia W. ★★★★★

These are the pants I reach for every single evening now. The bamboo rib knit has a nice weight to it that keeps me warm without any bulk, and they've held their shape perfectly through several washes. Honestly, I forgot I was wearing them.

Adam K. ★★★★★

The ribbed bamboo fabric is surprisingly stretchy and soft against the skin, not clingy or itchy like other base layers I've tried. Wore them under jeans for a chilly walk and then kept them on for the whole evening on the couch — warm without feeling suffocated, which is exactly what I wanted.

Alexander B. ★★★★★

These are my go-to pants for cold mornings now—the ribbed weave keeps the warmth in without that stiff, scratchy feel I usually get from base layers. I basically live in them on the couch and they still look neat enough to answer the door in.
