The Petzl Bandi chalk bag is deceptively simple. The streamlined design enhances your climbing experience, with its round shape and large opening that is sized to accommodate the entire hand. The bag can easily be opened with only one hand should you forget to open it before you start climbing, and the liner is sewn into the bottom of the bag, eliminating any chance of pulling it out while withdrawing your hand. This practical closure system consists of a drawstring and cordlock that prevents chalk from spilling out during transit. The rigid rim maintains the shape of the bag even after it has been packed for travelling. It also features a brush loop and comes with a removable waist belt.
