About Envelop Protective Covers

We started with the big guns.

We originally developed our patented technology for military gun covers that would protect guns and other topside equipment for the U.S. Navy in a tropical marine environment – the perfect incubator for corrosion, combining heat, moisture and salt.

Today, 13,000 military gun covers from Envelop Protective Covers are at work in metal-eating environments where they’ve reduced corrosion by 90% on 50-cal. machine guns, 25mm guns and 155mm howitzers.

Technology proven for and by the military:

U.S. Navy
U.S. Coast Guard
U.S. Marine Corps
U.S. Army

For your guns.

We’re making the proprietary metal-protecting technology developed for military gun covers available to hunters and collectors because it’s just as effective for your guns as for military guns.

This 155mm U.S.M.C. howitzer gets Envelop protection. Don’t your guns deserve the same?
