Why We Like The Mammut Boulder Cube Chalk Bag

Whether we're bouldering indoors or out, the Mammut Boulder Cube Chalk Bag is in tow. The fleece lining keeps chalk dust out of our nostrils and ensures an even coat on our hands, while the stout design makes it harder for our spotters to accidentally kick it over. When it's time to head home, we simply cinch the top closed to lock our friction dust inside.

  • Water-repellent finish fends off light precipitation
