Bison hard cases are American-made and tough as nails. Similar to our hard cooler line, our protective hard cases are designed to take a beating while still keeping your gear safe. Dust, dirt, moisture, collisions and scratches are no match for these cases. Engineered to keep firearms, camera/video equipment, drones, expensive tools, and military gear protected from the elements, Bison hard cases are the premium product on the market. Each case features an o-ring that makes it air tight and water tight up to 3 feet. An automatic pressure valve adjusts to its environment and the TSA/ATA approved lock holes are perfect for airport travel. Spring-loaded latches keep the case closed and your gear secure.
