Featherweight Performance.

Arc'teryx designed the women's Phase SL Boxer as ultra-light performance underwear, providing users with the highest level of moisture management for outdoor activities. The boxer has flatlocked seam construction for enhanced next-to-skin comfort. A gusseted crotch design allows wearers extra maneuverability during morning exercise routines and weekend ski adventures. At only 30-grams, and featuring a minimalist Arc'teryx design, there are few women's boxers that offer as much lightweight support and technical style.
