The Capilene Thermal Weight Bottoms for Women deliver exceptional warmth and breathability in a midweight base layer, thanks to soft Polartec Power Grid fabric and a gusseted crotch for mobility. They excel for high-output cool-to-cold backcountry activities like skinning uphill and climbing, though the see-through fabric may wear less durable over time and odor can linger.
Durable synthetic base layer tested for skiing, hiking, climbing, and snow play, offering a strong warmth-to-wicking balance and fast drying. The high-rise, comfortable fit with flatlock seams layers well under other layers and moves well with activity. A noted drawback is that the fabric tends to hold odor after use.
The Arc'teryx Rho Bottom is a lightweight, versatile long underwear bottom designed for multi-sport use. It features a high-rise waistband, a stash pocket, and a comfortable, stretchy fit that works well worn alone in cool conditions or layered under ski gear; it’s not the warmest option for the coldest months and is priced at a premium.
