Details Petzl Sakab Bouldering Chalk Bag  A freestanding, semi-rigid bouldering chalk bag, the Sakab's opening is large enough for both hands to dip into your chalk. Its magnetic roll-top closure keeps the chalk securely inside the bag. It has two handles, for transport and to hang it at hand height. A practical choice, with a brush holder and two zipped pockets for separating stored items. Specifications SAKAB Bouldering Chalk Bag
