The ExoFit design is based on the concept of a single piece of material constructed in the shape of an "X" that wraps around you for the ultimate in no-tangle donning and comfortable security. The materials are soft and light-weight, yet extremely durable. The shoulder, hip and leg padding is built-in so it can't slip. The breathable Dri-lex lining guarantees you'll stay dry and comfortable every day. And the quick-connect buckles are fast, efficient and totally secure!
