Arc'teryx Phase AR Singlet Top - Women's
A next-to-skin layer you'll wear so often, you're tempted to buy a spare.
Arc'teryx crafted the Women's Phasic AR Singlet Top with its smooth, stretchy Phasic AR fabric to create a year-round base layer you can wear on its own or under winter midlayers. Phasic AR's inner slightly-fuzzy face draws perspiration away from your skin and lets it evaporate from the smooth outer face. A racerback cut stays firmly in place as you lift your ice axe, plant your ski pole, or reach for a higher hold on a summer crack climb.
