Yeti easily makes some of the best coolers around, and not all of them require a lot of space of a set of wheels. Their latest is a brilliant cooler backpack that’ll make you the life of the party, even if it’s just a party of one. The Yeti Hopper BackFlip 24 backpack cooler’s shell is made with waterproof, UV- and mildew-resistant DryHide. It can hold up to 20 cans of brew (or other, less desirable beverages), and it’s totally leakproof (even the zippers). The shoulder straps, chest strap, and waist belt provide a stable fit, and there’s even a feature called HitchPoint Grid, which is essentially four sets of looped webbing for to attach gear, etc. The top handle and two side handles provide additional carry options, as well. It might just be the ultimate portable outdoor cooler for those on the move.
