Airline-approved Outback is ready to go to work for you. It's a solid, composite hard case with the upper and lower lids in one solid piece, free of seams, joinery or fasteners. Constructed of high-density polyethylene material, Outback has a uniquely-engineered design that absorbs impact by flexing when struck. Outback is lightweight, and its exterior is scratch-resistant. Wide, stable rubber feet stand Outback upright to keep the body safely above the ground. You'll appreciate the peace of mind that comes with Outback.
