Yeti Hopper Backflip 24
Whether you’re hiking to a slopeside picnic spot or going to a party at a different employee housing complex, the Yeti Backflip 24 is a great all-around backpack cooler. With enough room to carry lunch and beverages for a handful of your friends, it's also waterproof and will keep your perishables respectably cold even in hot summer temps. A more-tall-than-wide frame as well as a sternum strap and waist strap make it a great backpack cooler no matter what you’re getting into. And yes, it’ll keep your beers cold—unless you’re an idiot who keeps the top open all day. [$300; yeti.com] - Ryan Dionne, Contributor.
