Bring the Mammut Crashiano Pad when you're planning on flying off the big boulders. Mammut made this beast out of high-strength nylon to take a beating, and its Swiss quality foam consists of three layers that should keep you off the rocky ground. The top layer runs over the folded center to eliminate any dead spots. Mammut also added padded backpack straps, a hip belt, an integrated dirt cover for the padded back panel, a floor mat for your climbing shoes, and a zippered pocket for your phone.
