The Transpack TRV Pro Ski Boot Bag is designed for the world traveler who doesn't leave home without their boots, helmet and gear. This bag is an Isosceles Storage System™ that will hold everything you need for the mountain. If you don't ski, that's ok because this bag can hold snowboard boots instead. The fabric is super tough and water resistant coated with 168 ballistic nylon. The front vertical zipper provides extra access to the large central compartment.
