Purpose-built for paddlers for friction-free strokes, the NRS Men's HydroSkin® 0.5 Long-Sleeve shirt is the ultimate lightweight, immersible base layer. Layer the HydroSkin long-sleeve under splashwear for added insulation or mix and match with Hydroskin bottoms instead of wearing a full sprint wetsuit. Four-way-stretch PowerSpan™ exterior allows unparalleled range of motion and soft ThermalPlush™ lining delivers extra comfort and 0.5 mm Terraprene™ neoprene with heat-reflecting titanium locks in your body's warmth. A durable water repellent (DWR) exterior coating sheds water to help reduce evaporative cooling. The underarm panels feature H2Core Rashguard material for friction-free strokes and chafe-free comfort. Its form fit restricts water entry and intensifies the insulation properties. Thread the drawstring on board shorts or other bottoms through the hemloop to keep the HydroSkin from riding up.
