Arc'teyx Rho Bottom Women's

When the temperature drops and the approach gets long, the last thing you want to think about is your base layer, and that's exactly the point of the Rho Bottom. Built from Torrent stretch fleece, it sits close to the skin and stays there, wicking moisture away while trapping just enough warmth to keep you comfortable through steady efforts. The triangle-shaped gusseted crotch and baby-merrow stitch construction mean you can move, stretch, and climb without the garment fighting back, and the low-profile waist with high rise makes layering underneath your shell or ski pants genuinely easy instead of an afternoon wrestling match. Whether you're touring, skinning up for freeride laps, or just fighting off a cold resort day, the Rho Bottom works quietly in the background so you can focus on the descent.
