Most climbers focus on the weight of carabiners, quickdraws and cams, not their heavy chalk bag. Metolius decided to do something about that and created the cylindrical Ultralight Chalk Bag. Cylindrical-shaped Chalk Bag. Ultra-Lightweight: Up to 70% lighter than standard chalk bags. Small loop holds a brush (not included) for cleaning off holds. Includes a lightweight webbing belt with side-release buckle. Material: 100% Nylon. Recommended use: Climbing. Weight: 1.7 oz.. Spot clean. Imported.
