Arc'teryx Mainstay Shirt LS Mens

Upgrade your flannel. The Mainstay delivers all the things you love about flannel – softness, warmth, casual style – but adds moisture wicking performance and stretch. The brushed polyester flannel feels great, dries fast, and resists wrinkles. Mechanical stretch and articulated patterning combine for freedom of movement – great for bike commutes – and double back yoke gives a clean, finished look.
