This evolution of the YETI Hopper M30 soft cooler bag in navy delivers on a top customer request: a wider, easier opening. Through thoughtful engineering and thorough design exploration, the new Hopper M30 replaces a zipper with magnets. This is YETI’s first cooler to put the HydroShield Technology to work for an ultra leak-resistant, yet easy to use closure. This new closure system is two-fold, yet easier than ever to open and close. Plus it opens wide, making it a breeze to grab a few cold ones, as it should be. The dual, Quick Release Buckles ensure that your YETI Hopper M30 Soft Cooler Bag can withstand being tossed onto the boat or truck without opening unexpectedly.
