Arc'teryx Rho SV Bottom Women's

When the forecast reads brutally cold and the objective is still on, the Rho SV Bottom earns its place next to skin. This is Arc'teryx's warmest base layer bottom, built with a 210gsm hollow-core fleece that traps heat without weighing you down, so you stay comfortable through long approaches, lift lines, and exposed ridgelines. The fabric is soft against the skin, breathes well when you're working hard, and is engineered to minimize shedding, so it stays looking good wash after wash. Articulated patterning and stretch move with you through big steps and awkward transitions, while seams are placed to reduce chafing during long days in the backcountry. A low-profile thigh pocket keeps a lift pass or energy gel within reach without adding bulk under your shell. Designed for snow and freeride pursuits in severe cold, this base layer is the kind of piece you forget you're wearing, which is exactly the point.
