Bouldering mat

A bouldering mat or crashpad (also sketchpad) is a nylon-enclosed multi-layer foam pad used for protection when bouldering. Bouldering mats help prevent climbers from injuring themselves from the continuous and repeated falls onto hard or uneven surfaces that are associated with projecting a bouldering problem.^[1]

Some modern pads include a hinge to fold the pad over into a more compact form (a 'hinge mat'), and some also come with shoulder straps. and even waist straps, for easier carrying to and from the bouldering area. The first commercially available bouldering mat, the "Kinnaloa Sketchpad", was designed and produced in 1992.^[1]
