Pelican™ Air cases are the first in a series of remarkable innovations engineered by Pelican, the pioneers of protective cases. The Pelican 1535 Air Case is made from a proprietary Polypropylene blend, making it the lightest premium Protector Case™ in Pelican's line. This case includes Pelican’s Pick N’ Pluck™ system to match your ever-changing travel needs, a retractable handle and stainless-steel bearing wheels to make for easy transportation. An ABS quick release lock system and reinforced lid holes for personal locks flank the carrying handle. An automatic purge valve keeps water and dust out while balancing air pressure.
