The Thule Subterra 2 Wheeled Duffel Bag is built to handle gear-heavy expeditions and multi-week trips to remote locales. The 75-liter capacity safely stores a huge amount of clothes and gear, and it is all easily organized by the fold-flat divider and interior compression straps. Our cargo is completely protected by tough 800-denier nylon, which is treated with a water-repellent coating to cast aside light moisture on rainy days and boat trips, and the polycarbonate back panel absorbs impacts from rough handling and bumpy car rides.
