A high-density fabric that's waterproof and resistant to mildew, punctures and UV rays so you can use it in places where those off-priced coolers won't last. Like in the bottom of your canoe. Or strapped to your camel. This fabric is found in things like survival suits. It should withstand most of the hazards you can throw at it.
The liner is made from an FDA-approved food-grade material that doesn't contain dyes or recycled plastic considered harmful to humans. So your brie won't come out tasting like an inflatable boat. Unless you don't like brie and believe it already tastes like an inflatable boat.The closed-cell rubber foam used for insulation in the Hopper Flip 12 offers far superior cold-holding ability. If you use common sense measures (like not leaving the cooler open in direct sunlight for extended periods) you'll find it will keep your ice in a frozen state much longer than ordinary soft coolers. Those vertical straps with the sewn-down loops on the front and back of your Hopper Flip 12 do serve a purpose. Two D-ring tiedown points provide multiple ways to secure your Hopper and attach the shoulder strap. With a detachable shoulder strap and three reinforced handles, you've got options on how to make the load easier to carry.
