Lightweight, weatherproof and able to withstand the rigors of airline travel, our premium Hardside series was designed with the same attention to detail as the rest of our travel gear and built with durability top of mind. The Transporter 4-Wheel Hardside Carry-On 22″/40L is sized to fit most major airlines’ overhead bin requirements. The tough outer shell is sustainably crafted from 80-percent post-consumer recycled polycarbonate. A gasketed frame closure offers maximum weather protection and oversized wheels roll smoothly over uneven surfaces.
