Mammut created the Magic Gym Bag so your chalk doesn't creep into every aspect of your life. Pack this gym bag with your post-workout clothes, refill the removable chalk bag in the bottom compartment, and be on your way. When you get to the gym, whip out the chalk bag, crush some problems, and then grab your clean clothes from the top compartment to go change. This gym bag stores your chalk out of the way and separated.
