What Our Gearhead(R) Experts Are Saying:"I've used this for quick work trips and weekend trail missions, and it handles both easily. The oversized wheels roll smoothly over rough pavement, and the wide opening makes packing bulky gear simple."Weekend flights, road trips, and quick escapes all demand a bag that keeps up. The Thule Chasm is built for movement, giving us the durability of a rugged duffel with the ease of a wheeled carry-on. Constructed with weather-resistant tarpaulin fabric and a molded polycarbonate back panel, it's designed to absorb the bumps and scrapes that come with travel. The oversized rear wheels glide smoothly across uneven sidewalks and gravel parking lots, while the V-channel telescoping handle tracks straight through busy terminals. Inside, a wide-mouth opening and spacious main compartment make packing straightforward, and a large internal mesh pocket separates clean clothes from dirty layers or shoes. External compression straps let us adjust the profile depending on the load, and when we need overhead compliance, the internal max-fill marker keeps dimensions in check.
