The Gap Stopper is a quad-fold bouldering accessory that’s designed to fill gaps and smooth out landings.

Lightweight and versatile, it can also be used to cover slabs and boulders in landings or add an extra layer for sit starts. It has multiple handles on the edges for easy transport between problems and a large footprint to smooth out landing zones. The Gap Stopper also has an added carpet swatch in the corner for cleaning off shoes before stepping on the rock.
