This trolley bag makes travel easy. At 40L, it’s set to fly. It’s also designed to be super lightweight and maximize the amount you can pack in your carry-on. The wheels are sturdier than the average trolley with 80mm diameter to tackle bumpy terrain. Bonus: They are easily replaceable with standard in-line skate wheels. The interior has compression straps as well as a full-size mesh pocket. The trolley’s fabric is durable 420D poly. It has two grab handles as well as a 2-stage, telescoping, anodized-aluminum handle. The Sport Expedition Trolley is designed to be used with the Sport Expedition Bag, that slides onto the trolley handle. Extra features include a lockable zipper on the main compartment, and molded foam logo detailing on the back.
