- When you’ve got a few pals, a few refreshments, but the lake is a few miles down the trail, the YETI®  Hopper®  M12 Backpack Soft Cooler has your back. It’s the perfect refreshment hauler for any day trip or side mission. This comfortable, easy-to-open (and stay open) cooler was designed to fit wine bottles and hold up to 20 cans* of your favorite beverage for days in the summer sun. Attach accessories such as the Rambler®  Bottle Sling  Gear Case to the HitchPoint™ Grid for even more hands-free function. The durable MagShield Access uses a strip of ultra-strong magnets that keeps your cooler closed and leak-resistant. And the Kangaroo Pocket lets you easily stash away keys, a wallet, or phone so you can get going.
