Designed with durability and versatility of use in mind, the Cypher Double Boar Hair Brush accommodates most small to medium carabiners for clipping directly to your climbing harness for faster retrieval and put-away, or, you can simply push it into the elastic loop on your chalk bag for the more traditional brush carry. The Brush has boar’s hair bristles for general brushing of holds and also includes a second set of darker bristles that are stiffer and shorter for cleaning stubborn or caked chalk on climbing holds. The bombproof handle enables aggressive use without fear of bending or breaking. Don’t let that over-chalked hold stop your sending again!
