Phase AR Zip Neck LS Men’s

Mid-weight, zip neck base layer appropriate for cooler temperatures, high-output activities. Hybrid mapping of Phasic™ AR (in the body) and Phasic™ SL (in the underarm area) fabrics in addition to the flatlock construction and next-to-skin fit eliminates excess bulk and rapidly transfers moisture for efficient evaporation. Benefits include improved temperature regulation and layering.
