Meet the Yeti Hopper 20, our ice-for-days portable cooler. No matter where you haul it - from campsite to boat deck - the Dryhide Shell and nearly indestructible straps will stand up to an abundance of abuse in the field, while the HydroLok Zipper (a design borrowed from HazMat suits) is completely leakproof, eliminating spills and locking in cold. Holds 18 cans, a limit of rainbow trout, or 20 pounds of ice.
