Pure and simple serious padding, the Impact crash pad provides the same dimensions and cushioning of the Drop Zone without the pocket or flaps. If you don’t have much to carry, the Impact offers a lot of pad at a value with two and a half inches (64 mm) of cushy open-cell foam and an inch (25 mm) of force-dissipating closed-cell foam. Using a taco design, the Impact is a snap to fold up and carry with its minimalist design, stainless steel buckles, padded shoulder straps and hip belt.
