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 that 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 to allow the addition of standard size padlocks. It also has hinges with integrated feet that hold fast under impact, and create a flat surface for upright stability. It has three double-layered, soft-grip, solid-core handles; a lightweight, retractable, telescoping handle and rugged in-line wheels for easy transport.
