PETZL - SAKAPOCHE, Chalk Bag with Pockets for Climbers ALL IN ONE: With the SAKAPOCHE's ergonomic shape and rigid rim, it's easy to get your hands in there. The exterior pocket let you stash keys, money, snacks, and anything else you need on hand. COMFORTABLE: The soft fabric won't cause discomfort when wearing a pack or when you're pressed against a rock. ONE-HANDED OPEN: The drawstring and cordlock closing system allow you to open the bag with one hand when you're climbing. FOR ALL BRUSHES: The rigid brush holder on the side has two retainers to better hold all types of brushes. CHALK IT UP: The inner liner is sewn to the bottom so it doesn't flip out when you pull your hands out.
