The Hopper Flip 12 is the soft cooler most testers reach for when leakproofing and durability matter more than price. GearJunkie named it Best Overall and CleverHiker logged just under four days of ice retention in a melt test. The rigid cube holds 24 cans, and the HydroLok zipper is genuinely watertight once you accept that it takes two hands. It is expensive, but it is the cooler that survives the most abuse.
- — Held ice for just under four days in CleverHiker's controlled melt test before reaching 50F internally
- — Leakproof HydroLok zipper kept water in even when tipped or carried sideways
- — At $250 it is one of the most expensive 12-liter soft coolers sold
- — HydroLok zipper is stiff and needs two hands plus zipper lube to slide smoothly
