Thule's durable duffel bags are built to cope with tough journeys. The large-capacity shoulder duffles are designed to support your outdoor excursions while duffle roller models are built to easily navigate airports and hotels. A range of sizes and colors ensure your duffel bag will match you and your adventure. The Thule Subterra 40L duffel bag can be carried as a duffle backpack or a shoulder bag (all straps tuck away when not in use). All bags in the Thule Chasm range of rugged, weather-resistant duffels provide removable backpack straps.
