YETI’s tough-as-nails Hopper® M30 Soft Cooler has a major update. Their signature wide-mouth opening has been reengineered to stay open with ease and close tight with a gentle push. A strip of ultra-strong magnets locks in cold while Quick-Release Buckles provide extra security through choppy water or when riding through rough terrain in the bed of a truck. 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. MAGSHIELD ACCESS Durable and powerful magnets create an ultra leak-resistant shield that stays open when you need it and snaps closed with a gentle push. COLDCELL™ INSULATION Closed-cell foam offers impressive cold-holding capabilities, helping keep your frosty goods ice cold. LEAKPROOF LINER RF Welding used to eliminate stitching and provide leakproof seams in the interior liner. DRYHIDE™ SHELL High-density fabric withstands punctures and UV rays. To help extend the life of the cooler, both the interior and exterior materials are treated to be mildew resistant. HITCHPOINT™ GRID Securely attach your SideKick Dry® Gear Case or load it up with zingers, nippers, bottle openers, and multitools. DOUBLE-STITCHED CARRY Every pick-up point is reinforced so you can handle more weight than you'd prefer to carry.
