Now there is a drysuit that works as hard as you do. Get the job done with the NRS Extreme SAR. Equipped with glow-in-the-dark Energlo, this drysuit is the whole package. Energlo arms help ensure you'll be seen even in little or no light conditions. Energlo is a revolutionary fabric that is waterproof, breathable and highly abrasion resistant. This fabric will never lose its ability to glow-in-the-dark and will glow brightly for up to three hours after being exposed to light. Designed specifically for hardworking rescue customers, the 400-denier TriTon fabric will hold up to years of abuse. A Heavy-duty YKK waterproof men's relief zipper lets you answer nature's call without having to take the whole suit off and with the help of the internal suspenders, you can comfortably wear the top of the suit down around your waist while away from the water.
