DESC: The Transpack& ice skate backpack features the Isosceles Storage System, a unique design with vented skate pockets and a reinforced central compartment. Moisture from your skates is drained and vented through grommet air/water holes, keeping the objects in the main compartment dry and protected. This backpack is constructed with a super-tough, 600 denier, PVC-coated polyester fabric and adjustable, neoprene-padded shoulder straps.
