The MSD575 WR Water Rescue Drysuit is a traditional fitting, durable dry suit designed for rescuers who face the challenge of moving water and urban flooding. The suit combines the robustness of Mustang's Tactical Operations Dry Suit, with the high visibility and padding needed in a swift water or urban search and rescue (USAR) environment. The breathable GORE-TEX is supplemented with Kevlar patches on hip, knees, arms and cuffs to provide extreme abrasion and puncture resistance against rocks and debris. The suit's internal suspender system provides an almost "custom fit" over the range of sizes, ensuring maximum mobility. Mustang's patented Closed Comfort System (CCS™) can be worn loose to provide comfort out of the water and can quickly be drawn tight to keep the water out. The adjustable seal also provides increased durability compared to traditional latex seals. The diagonal waterproof entry zipper and horizontal waterproof relief zipper ensure easy entry and crew comfort during extended operations. Thermal performance of Mustang drysuits are dependent on the type of undergarment worn.
