The Ivan is Chrome's largest, 100% welded-waterproof rolltop backpack and part of WWII inspired Militia line. Chrome made its original Militia bags to haul wetsuits and beer to and from the beach. All Militia bags feature 100% welded-waterproof main compartment that can hold ice-cold beer and keep your stuff dry in a downpour. A zippered compartment keeps wet/dry separate. Outside pockets with stainless-steel hardware for storing small stuff.
