Sensitive equipment requires protection, and the Pelican Protector Case has been providing that since 1976. It is designed to endure even the most rigorous of conditions - from temperatures in the Arctic to the heat of war - and it's tough enough to survive them all. Crafted in the USA, these cases come with an automatic purge valve for equalizing air pressure, a watertight silicone O-ring lid, over-molded rubber handles and stainless steel hardware. They also feature large 2-person fold down handles, four robust polyurethane wheels with stainless steel bearings, an open cell core with solid wall design - strong yet light weight - as well as a retractable extension handle. In short: Watertight, crushproof and dustproof.
