The Pelican iM2300 Storm Case without Foam (Black) is an injection-molded case made of HPX high performance resin, that is virtually unbreakable, dent-resistant and shatter-resistant. It is tough, rugged, lightweight, airtight and watertight. There is a permanently attached Vortex valve that 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. It is carried by a double-layered, soft-grip, solid-core handle that provides strong, durable comfort.
