The M30 Hopper is Yeti's carry-the-day, tough-as-nails soft cooler that's updated with wider mouth for easier loading and cleaning. We love that it features the same durably waterproof DryHide shell with a leakproof lining and ColdCell insulation as Yeti's other soft coolers, except this one's magnetic closure secures for watertight storage when we're walking from the car to a picnic.
