The Hopper BackFlip 24 fuses the durability of the Hopper Flip with a new design that's convenient to carry. It's our first cooler designed to be carried like a backpack, featuring the best technology of both worlds. Bigger and wider than its Hopper Flip counterpart, Hopper BackFlip is designed to efficiently distribute the weight of your things, while the ergonomic shoulder straps make adventure more enjoyable. Even more, a front strap and waist belt are included to provide added stability and security. And like the rest of the Hopper family, it features superior cold retention, a 100% waterproof zipper and a rugged DryHide shell. So head out to your favorite deep-sea fishing destination, because that backpack cooler isn't going to slow you down. Cooler at 100%. 100% backpack.
