Black Diamond Gapstopper Boulder Accessory Mat

Sorry, this product is out of stock. We can notify you when this product is available:

The Black Diamond Gap Stopper: A must-have quad-fold bouldering accessory mat for any keen boulderer. Fill gaps, smooth out landings, and cover slabs and boulders with ease. Take on new challenges with its lightweight versatility and multiple handles for transport. There's also a carpet swatch on one corner to wipe your shoes down before every climb.

The Gapstopper folds up and can be wedged inside your main bouldering pad. However, if you wish to carry 2+ pads, then we would suggest investing in the Black Diamond Piggyback Carrying System as well. Not only does this keep all your pads together for easy carrying, but you can also carry all your climbing essentials such as shoes, snacks and a guidebook in the zip-up pouch. How handy is that!
