Exclusive NRS TriTon™ fabric provides exceptional breathability in a waterproof drytop. TriTon™ utilizes 450 denier, 10 oz. polyester tricot material to enhance vapor transfer to the outside while creating an impenetrable water barrier. Stretch fabric has been added across the shoulders to mold the jacket to your body's movements. Armored elbows enhance durability. Double-pull hook-and-loop waist closure for a precisely engineered fit. Generously patterned for layering and a full range of motion. Precision-taped seams and durable neck and wrist Latex gaskets seal out water.
