THROW A DAY'S WORTH OF SNACKS AND BEERS ON YOUR BACK. The Hopper® M20 Soft Cooler allows you to put the day on your back - literally. This hands-free cooler comfortably straps on like a backpack to keep you mobile, while a strip of ultra-strong magnets keeps the cold locked in. The new MagShield Access opens wide so you can easily load in beer, ice, or your favourite sandwiches. Attach accessories such as the Rambler® Bottle Sling or Sidekick Dry® Gear Case to the HitchPoint™ Grid to keep useful gear at your fingertips. The Hopper® M20 is the cooler that goes where other coolers can't. WARNING: Do not leave your soft cooler open in the presence of children and animals. Entrapment and suffocation can occur.
