The Long Sleeve Nano Paddle Jacket utilizes lightweight, hydrophobic 2. 5-layer polyester fabric that stays lighter, dries faster, breathes better, and prevents condensation. An alpine-inspired fit allows for unrestricted movement while eliminating excess fabric. Neoprene neck and wrist bands comfortably keep water out. The articulated cut gives you room to move without being restricted or lost in excess fabric. A simple one-piece sticky neoprene tube tunnel keeps water out and reduces bulk around your midsection.
