Mammut Kelly Chalk Bag for Magnesium - Black

At the base of a limestone crag, a climber dips into the Kelly Chalk Bag, its wide, stable opening allowing a quick, full-hand chalk-up without fumbling. The fleece lining evenly coats the skin, while the drawstring closure keeps magnesium dust contained between burns. A brush holder on the side keeps a stiff-bristled brush within reach for cleaning holds, and the adjustable waist belt ensures the bag stays put through high steps and dynamic moves.
