Made for comfort, The YETI Hopper M20 is a backpack cooler that can carry up to 18 cans of your favorite beverage (or 26 pounds of ice) while keeping your hands free. This cooler's easy-to-use magnetic closure and wide mouth opening keep cold drinks at your fingertips. Attach accessories such as YETI's Rambler Bottle Sling or Sidekick Dry Gear Case to the cooler's HitchPoint Grid to keep gear ready to grab. The top folds over and clips with two buckles for easy and secure transport to your favorite outdoor spots. Powerful magnets create an ultra-leak-resistant shield that stays open when you need it and seals closed with a gentle push. Closed-cell foam offers impressive cold-holding capabilities, helping keep your frosty goods ice cold. High-density fabric withstands punctures and UV rays. Securely attach your SideKick Dry gear case or load it up with the YETI molle bottle opener, molle zinger or other multitools. To help extend the life of the cooler, both the interior and exterior materials are treated to be mildew resistant.
