Each case comprises an inner and outer shell and an air bladder. The outer shell is a 1,000 denier, urethane-coated material for extreme durability and weather resistance. The inner shell comprises a Berry-compliant, 500 denier, urethane-coated material. When deflated, the gun case rolls up incredibly small, yet offers complete encapsulation of your firearm between two 3-inch-thick air bladders when fully inflated. Air Armor Tech cases use our 3-Pipe Inflation System and zip up tight with a YKK™ water-resistant zipper. These cases stand up to the most extreme blunt-force trauma.
