The Mens Arcteryx Phase SL Boxers are part of Arc'teryx's new Phase Base Layer line in the Super Light weight. Made from a hydrophobic double knit textile without insulation, the Phase SL Boxers effectively wick away moisture and disperse it throughout the baselayer for quick-drying comfort. The mechanical stretch of this Arcteryx base layer provides athletic comfort and eliminates elastic yarns that can absorb and hold moisture against your skin. Unlike other synthetic layers, the Phase SL underwear features anti-microbial silver ions within the fabric to eradicate odors; the highly technical process for encapsulating silver-ions in the fibers provides effective and long-lasting odor control. The excellent moisture wicking performance makes the Phase SL shorts ideal for stop and go activities when dry base layers are a must. Technical aspects aside, the stretchy Arcteryx Phase SL Boxer features anatomical shaping and gusseted crotch for superior fit and excellent mobility. The Mens Arcteryx Phase SL Boxers keep you dry and comfortable when active.
