The Switchback's secret power is its quick-drying, ultra-stretchy fabric—a blended polyester that will crush your cotton long-sleeve shirt when it comes to everyday comfort and performance. The switchback is a go-to when you want soft, cozy feels in a breathable long sleeve—which is pretty much...always. Pull on the Switchback when you're out and about with your friends or hitting out and backs in the woods with your hiking crew.
