Boulder Brush Organic
Description & Tech Specs
The Ocun Boulder Brush Organic comes in two sizes, each using a different natural bristle material suited to different hold types.
The Small uses boar hair bristles, which are softer and better suited for delicate holds, slopers, and textured rock where aggressive scrubbing could polish out the surface. It weighs 17g and has an asymmetric head that tapers from 13–11mm.
The Large uses sisal bristles, a stiffer plant fiber that handles more aggressive cleaning on positive holds, pockets, and heavily chalked crimps. It weighs 27g with a head that tapers from 16–14mm.
Both sizes have a wooden handle with a lanyard hole for clipping to a harness or crash pad strap.
