Combining strength and lightness, the 1535TRVL Wheeled Carry-On Air Case with Lid Organizer and Packing Cubes in black from Pelican is watertight, crushproof, dustproof, and optimized for travel. For travel by air, Pelican has aggregated available airline rules for maximum overhead and check-in dimensions with the goal of creating a case that conforms to their requirements. Of course, there will always be exceptions, so it's wise to contact your carrier before departing. Your 1535TRVL case is made of a super-light, proprietary HPX polymer (with honeycomb structural elements) that is up to 40% lighter than most other Pelican polymers. This confidence-inspiring design has been drop-tested on concrete on all sides and corners while loaded with gear. The case is also tested with a 28-pound steel dart dropped from a height of three feet, submerged for 30 minutes at a depth of 3.3 feet, and the wheels are roll tested over 1000 yards with loads at 5 mph. The case has ABS double-throw latches that accept a user-supplied padlock, a watertight O-ring gasket, an automatic purge valve, and stainless steel hasp protectors. Users will appreciate the conic-curved lid shape, the rubber overmolded handles, and the extending trolley handle. For easy case identification, a removable polycarbonate card holder may be placed on the front or side of the case. Lid organizers have zippered compartments for stowing larger items and see-through mesh pockets secure passports and cables. Packing cubes keep gear tightly bundled and allow you to arrange your gear by stacking or grouping side by side.
