The Organic Climbing Simple Bouldering Crash Pad is an option for boulderers who want the highest quality foam.There is a solid 1" layer of foam that extends across the entire top surface of the pad, and underlying foam is split with a hinge. This allows for a seamless landing surface. It also protects your foam from deteriorating, which can result from constant folding in a taco-style pad. In addition, it keeps the folded dimensions tight and square, even with the stiff foam we use, so you and still tuck your mat neatly into your car or closet.
