Phase AR Bottom Women's

A women’s midweight base layer for high output in cooler temperatures, the Phase AR Bottom is made from next generation Phasic™ AR. An Arc’teryx fabric engineered to provide insulation, dry quickly, and offer performance stretch, Phasic™ AR uses different polyester yarn structures on its interior and face to most effectively wick and disperse moisture. Lighter weight Phasic™ SL panels at the back of the knees improve thermal regulation and reduce bulk. Updated style lines and improved fit.
