Bouldering mat

From Wikipedia, the free encyclopedia

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]

Modern pads can include a hinge to fold the pad over into a more compact form (a 'hinge mat'), and also come with shoulder and 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]

Design[edit]

A 'hinge mat' that is folded in two

Modern bouldering mats are made in a wide range of sizes and styles (and colors) and can be up to 8–15 centimetres (3–6 in) in thickness, and up to 1 by 2 metres (3 by 7 ft) in surface area (at the larger end).[2][3][4] "Bi-fold" mats (and even "tri-fold" mats),[4] allow the bouldering pad to be more easily transported to the bouldering area, however, the use of any "hinge" for easier folding introduces a point of weakness.[2][3][4] The term 'taco mat' is a single-section foam pad that bends in the middle when folded but has no hinge ('burrito mats' fold in three),[3][4] while 'hinge mats' are pads with two sections of foam connected by a hinge.[2][3][4]

Bouldering mats and crash pads typically have two or three different layers of polyurethane foam that are enclosed in a tough outer skin of typically 600 to 1000 denier nylon, or equivalent material like cordura.[3][4] Softer 'open-celled' foam below firmer, higher-density 'closed-cell' foam will prevent a climber's foot from sinking through the foam and either impacting the ground or getting stuck in the mat, which would increase the chance of injury.[3][2][4] The foam itself comes in various thicknesses, with smaller thinner mats used for sit starts, to cover gaps between larger mats, and/or to keep shoes clean and off the bare earth.[2][3][4]

Modern bouldering mats—and particularly the larger ones—usually come with some form of shoulder straps, and even waist straps, so that the mats can be comfortably carried on the climber's back while hiking to and from the bouldering areas.[3][4] Some mats also include pockets for storage or straps that allow climbers to turn the pad into a day-pack with their bouldering gear stuffed inside the folds.[2][3]

Use[edit]

A unique aspect of bouldering is the general lack of any requirement for climbing protection equipment that is associated with most other forms of rock climbing, such as sport climbing or traditional climbing.[5] While bouldering is essentially a free solo climbing format, the continuous and repeated falls associated with projecting a bouldering problem can damage the heel, ankles, shins (e.g. shin splints), and knees.[5][6] Bouldering mats are particularly important where the ground is very hard, uneven, and/or the fall area is littered with rocks.[5][6]

On boulders with potentially serious falls, such as in highball bouldering, the mats can be supported by spotters, who try to ensure that a falling climber lands on the mats.[5] It is common for modern boulderers to use multiple bouldering mats at a time to give complete coverage of the fall area below a bouldering problem.[5][7]

There is concern about the excessive use of bouldering mats and 'stacking' (i.e. layers of mats in a vertical pile), and whether 'stacked' mats is akin aid climbing that could help with a difficult 'first move' on a route,[8] and whether the use of 'stacked' mats reduces the objective danger—and thus the technical grade and challenge—of a given traditional climbing or highball bouldering route.[9] In 2023, Austrian climber Bernd Zangerl [fr] wrote in Climbing regarding the use of excess bouldering mats, "Today, we see landing zones resembling construction sites", and "... I wonder if it wouldn't be more honest just to toprope?".[10]

Origin[edit]

The earliest bouldering mats are associated with the Hueco Tanks bouldering area, and its associated bouldering pioneer John Sherman.[6] In a 2022 interview with Climbing, Sherman credited El Paso-based boulder climbers, Donny Hardin and Fred Nakovic, for the original idea "after a heel-bruising session not at Hueco, but City of Rocks, New Mexico".[6] In 1992, Sherman and Bruce Pottenger, from Bishop-based climbing gear manufacturer Kinnaloa, designed the first commercially available bouldering bouldering pad with the "nylon sleeve, carrying straps, dual-density replaceable foam" that would become the standard design in bouldering, which they sold as the "Kinnaloa Sketchpad" ('sketchpad' was an early slang for the mat).[6] By 2019, Climbing Magazine estimated that there were over 50 manufacturers of bouldering mats/crashpads worldwide.[4]
