Arc'teryx Women's Rho Bottom - Winter 2026/2027

A lightweight fleece base layer with excellent moisture management for cold weather. Cold days and long approaches call for breathable insulation, and the Rho Bottom is your base layer of choice for steady efforts when temperatures dip. A light next-to-skin fit ensures soft, fleecy comfort, as well as excellent heat trapping and moisture wicking. A triangle-shaped gusseted crotch delivers freedom of movement, with chafe-free seams throughout the garment. Designed with a low-profile waist and high rise for easy layering.
