The Men&';s Featherweight Hooded Long Sleeve Crew is built for year round comfort. We&';ve partnered with NuyarnA(R) to create best-in-class breathability and performance in a new ultra lightweight 125gm evolved Strategic Merino Blend that sees raw bamboo combined with twist free, technically spun merino wool. This fabric is faster drying, more air resistant, more elastic and astonishingly durable, not to mention soft-on-skin, odourless and offering 4-way stretch. UPF50+ sun protection and an ultralight hood make it adaptable across four seasons, while contoured side panels ensure to move with you as you fluidly navigate terrain.
