If you’re a serious boulderer, you need an arsenal of brushes. Now you don’t have to search the world over—or pay upwards of $50—for a complete set. For less than $30, you get five brushes—two are dual-sided, so it’s actually seven different styles, sizes, and textures for whatever type of hold or rock you might encounter. One dual-sided brush is the classic boar’s hair opposite soft horse hair, which was perfect on the two-finger pockets of Litz Pocket Problem (V8) at Horse Pens 40, Alabama. It comes conveniently wrapped in a pouch made of recycled billboard vinyl that rolls up for easy storage in a pad or pack. Sport and trad climbers take note: These are useful for cleaning intricate cams, biners, and other hardware, too.
