About this item

Reach the top with cleaner, grippier holds using Oso Supply Co's Blackcap Bouldering Brush. Named after Blackcap Mountain — one of Washington State’s tallest peaks — this brush is built for climbers who demand both performance and durability. The dense natural boar’s hair bristles sweep away chalk, dust, and grime without damaging rock or resin holds, restoring maximum friction for every send. An ergonomic, impact-resistant handle gives you excellent control and comfort, even when scrubbing awkward holds. Slim and lightweight, it fits easily into chalk bag brush loops or your pack, ready for action whether you’re training indoors or projecting outdoors. From MoonBoard sessions to alpine boulders, the Blackcap Bouldering Brush is a dependable tool for cleaner holds and stronger sends.
