For the world adventurer, the Pelican 1510 Carry-On Case will keep your equipment safe as you travel to the tallest mountains, most windswept deserts and raging rivers. This watertight, dustproof and crushproof case meets the Federal Aviation Administration's maximum carry on size. With a retractable extension handle and two wheels, you can roll the case, which makes transporting your heaviest gear or walking over long distances much easier. The strong, polyurethane wheels with stainless steel bearings deliver a smooth ride, while padlock protectors help keep your belongings safe. An automatic pressure equalization valve with an O-ring seal maintains the balance of the interior pressure, while preventing moisture from entering. The case uses easy open double throw latches and includes comfortable rubber-over molded top and side handles for your convenience.
