Crash pad
A thick, foldable foam pad placed on the ground beneath a boulder problem to cushion falls.
A crash pad is a large foam cushion, usually foldable with a fabric shell, that boulderers carry to the base of a climb and position under the likely fall zone. Pads combine a firmer foam layer to prevent bottoming out on impact with a softer top layer for comfort, and most fold in half with backpack straps for carrying between problems.
Pad placement is its own skill: a single pad rarely covers an entire landing zone, so boulderers often combine several pads, angle them to cover awkward or sloped landings, and adjust them as a climber moves higher and their potential fall line changes. Gaps between pads or pads that shift on impact are a common cause of rolled ankles.
When choosing a crash pad, think about the terrain you climb most, since a single large pad suits flat ground while smaller pads that combine easily suit uneven or bouldery approaches. No pad arrangement guarantees a soft landing, so spotting and careful pad management stay part of bouldering safety rather than something a pad replaces.
