When you"re out on the water on a wet day, it is nice to have some extra warmth and protection. And no one knows what you need better than NRS, being based out of the cool and drizzly Pacific Northwest. The company"s Disco Surf Shirt places sections of varying fabric at just the right places to keep you comfortable in your kayak, on your surfboard or paddleboard. Stretchy neoprene on the chest and back and HydroSkin panels on the sides and underside of the arms keep you warm even when you"re consistently splashed with or immersed in frigid water, and when evaporating moisture might otherwise cool you down. The HydroSkin fabric is composed of three layers: 4-way stretch fabric on the outside, a neoprene core, and ThermalPlush lining that adds extra insulation where it"s needed most. A titanium laminate adhesive layer in the HydroSkin fabric helps retain body heat, and a DWR (durable water repellent) treatment keeps water from soaking in by forcing it to bead on the surface of the fabric and run off. Spandex is placed at the underarms and collar of the shirt for ventilation and to prevent chafing. This high-performance shirt offers just the right dose of added protection and comfort to keep you out longer on those cool, drizzly days.
