Our all new Assault cooler is made for the desert, woods, mud, snow, any terrain your riding in. The new easy to clean material is ready for your abuse. Very durable outer material. It is guaranteed not to leak and includes a strap on each side so the cooler can be strapped down to the rack of your off-road vehicle or boat. The new outer material is 1000 denier vinyl and UV protective so the color won't fade in the hot sun. Not only is it stronger than any other soft-sided cooler, but tear resistant up to 375 pounds, waterproof, and anti-mildew. This new cooler is a must for any off-roader/boater or camper wanting a cold drink. It's the STRONGEST COOLER on the market!
