The Arc'teryx Rho LT Bottom is a lightweight fleece base layer for cold-weather hiking, skiing and climbing. It uses Torrent stretch fleece with a brushed inner face that traps warmth while wicking sweat, and it has a slim, athletic cut that layers under shells without bunching. Reviewers rate it highly for warmth-to-weight and next-to-skin comfort. Against heavier fleece tights it breathes better and packs smaller, but it is thinner than midweight options and the print colorway is polarizing.

Owners rate the Rho LT highly for warmth-to-weight, soft brushed feel and stretch that follows the legs on the move. Most criticism centers on the slim fit and on it being too thin for very cold days.
