To create the Men's A2B Polo Shirt, Arc'teryx had to bridge the cavernous gap between city life and mountain life. Arc'teryx infused this polo with some technicality you wouldn't expect or see elsewhere. The inner layer features a Polylain merino wool jersey with filament yarn for added strength and moisture management, while the merino wool keeps your body temperature regulated and even boasts some anti-odor properties. The outer layer is made from an anti-wrinkle, air-permeable fabric that packs well and wicks additional moisture. Beside the mechanical stretch properties, the A2B polo sports a trim fit and generous length for the ultimate in athletic movement and coverage.
