Pelican Cases are built tough. Made from a heavy-duty construction that is virtually unbreakable and is waterproof, dust proof and crush proof. With their unique o-ring seal on the inside lip of the case, water, moisture and dust are kept out, protecting your gear from damage. The built-in Pressure Equalization Valve will release built-up pressure inside your case when traveling in high altitudes. Our pelican cases come with optional pick n pluck foam that you can customize to specifically fit your gear. For easy mobility, install a Pelican Mobility Kit to your cube case for effortless transportation.
