A crashpad is a thick mattress specifically made for boldering. A crashpad is a supplement to a good spotter.A good quality crashpad has three layers. A middle layer that absorbs the energy of the fall, and two outer, more stiff layers, that give the crashpad structural rigidity. More importantly, the outer layers dissipate the load over larger area, so that a larger fraction of the inner layer will take part in cushioning the fall.
Crashpads are usually made so the fold in two or three, and with a set of shoulder straps and sometimes a hip belt.
