The NRS WRSI Whitewater Research and Safety Institute Current Pro Helmet has more safety features than its predecessor the NRS Current Helmet for improved protection and comfort out on the whitewater. This multi impact shell utilizes ABS plastic, polyurethane, and an EVA liner to dissipate impacts from trees and rocks. The Interconnect Retention System features nine EVA pads with different thicknesses to provide a completely customizable and very comfortable fit for any sized dome. The Current Pro also features removable ear pads that provide extra warmth and reduce impacts from waves, and the visor keeps rainfall and sunlight out of your eyes. WRSI's process uses wind powered technology to create products with less production waste.
