The Pelican iM2975 Storm Trak Case in Black is an injection-molded case made with HPX high-performance resin, so it is virtually unbreakable, as well as dent and shatter resistant. It is tough, rugged, lightweight, air and watertight. A permanently attached Vortex valve automatically adjusts air pressure without letting in water, and won't unscrew from the case. Press & Pull latches open with the push of a button, yet stay closed securely under impact or stress. The case has unbreakable molded-in hasps that allow the addition of standard-size padlocks. It has hinges with integrated feet that hold fast under impact, and create a flat surface for upright stability. You can carry it with the three double-layered, soft-grip, solid-core handles, or roll it with the lightweight retractable, telescoping handle and rugged in-line wheels.
