Combining strength and lightness, the black Pelican 1535 Air Wheeled Carry-On Case with Pick-N-Pluck Foam is watertight, crushproof, dustproof, and optimised 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 1535 Air 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. Not content to stop there; the case is also tested with a 28 lb steel dart dropped from a height of 3 feet, submerged for 30 minutes at a depth of 3.3 feet, and wheels are roll tested over 1,000 yards with loads at 5 mph. Fully-featured, 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 new, stylish conic curve lid shape, rubber overmoulded handles, and an extending trolley handle. Additionally, for easier case ID, there's an attractive, removable polycarbonate card holder that may be placed on the front or side of the case. Organising equipment is an easy and straightforward operation with the Pick-N-Pluck foam interior. Simply arrange the gear you wish to carry on the foam, try a variety of placements, and when you're satisfied, remove pieces of foam until items fit to your satisfaction.
