Straightforward padding for boulderers on a budget, the Impact 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 value with two and a half inches (64 mm) of cushy open-cell foam and one 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, removable, padded shoulder straps and hip belt.
