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 favorite sandwiches. Attach accessories such as the Rambler® Bottle Sling or SideKick Dry® Gear Case to the HitchPoint™ Grid to keep useful gear at your fingerprints. The Hopper® M20 is the cooler that goes where others can't. WARNING: Do not leave your soft cooler open in the presence of children and animals. Entrapment and suffocation can occur. WARNING: Hopper® Soft Coolers are not compatible with dry ice. Use of dry ice will cause airtight vessel to explode. WARNING: This product contains magnets. Placing near a pacemaker may cause interference.
