The Thule Chasm 90L Duffel Bag in Poseidon is built to withstand the rigors of heavy travel, overland expeditions, and rugged outdoor adventures. Engineered for extreme durability, this extra-large duffel easily accommodates long-weekend gear, heavy winter apparel, or bulky sports equipment while shielding your belongings from water, mud, and trail dust.
Crafted from heavy-duty, weather-resistant phthalate-free TPE laminate with a 1000D nylon base, the Chasm 90L keeps your gear dry and clean regardless of the environment. The oversized wide-mouth opening allows for effortless packing and quick access to buried items, while internal mesh zip pockets keep small accessories organized and within reach. Designed for ultimate versatility on the move, this duffel transitions instantly into a comfortable backpack using the included padded, removable shoulder straps. External compression straps keep your load stabilized, while padded grab handles make loading into truck beds, roof boxes, or luggage racks smooth and simple.
