If you're looking for a wet adventure, the Transporter 18 waterproof backpack is the ideal choice. Its IPX6-rated roll-top closure keeps the elements out, while simple internal organization keeps up to 18 liters of gear inside and in place. We used our comfortable AirScape back panel to give you a more stable fit. Whether you're hiking, biking, boarding or boating, keep your gear dry with our Transporter Waterproof 18 Backpack. Made from 100% recycled materials.
