WRSI (Whitewater Research and Safety Institute) helmet for non-motorized canoeing, rafting, kayaking and SUPing. We are surpised at how comfortable this helmet is! It's got a multi-impact shell with an EVA foam liner and polyurethane sub-shell to effectively dissipate impacts. If the water starts pushing your helmet back the interconnected strap system and O-Brace harness at the back of the head keeps the helmet in place. It is vented to keep you cooler and let the water drain, and the straps are adjustable for the perfect fit.
