The last cooler backpack you should need to buy
A bag that lives on boat decks, truck beds, and airport floors has to earn its keep. The JustinCASE is made for that life: a leakproof liner inside, Fidlock magnetic buckles that open one-handed and close without forcing, adjustable paracord straps that lash gear to the outside. All of it comes in at 3.1 lbs. Behind the hardware sits the promise. A lifetime warranty against defects in materials or craftsmanship, and 100 days to try it with a full refund if it is not right. You are not buying a season of use. You are buying the bag.

Built to last, backed for life
Gear that gets replaced every season is not cheap. It is just billed in installments. The JustinCASE is built the other way: a leakproof liner, Fidlock magnetic buckles that open one-handed, adjustable paracord straps that lash gear to the outside, all of it at 3.1 lbs. Behind it stands a lifetime warranty against defects in materials or craftsmanship. If a defect shows up, we make it right.
The first and only convertible backpack
All cooler, all dry storage, or both at the same time. The patented Dual-Mode Shelf is included with every JustinCASE and lets you split the interior however the day demands. No extra gear, no tradeoffs.
Try it for 100 days.

Questions, answered
Can I take it on a plane?+
Yes. The JustinCASE is sized to fit comfortably in a standard overhead bin, yet holds up to 30 cans and a bag of ice — reliable carry-on on the way out, high-performance cooler when you land.
How does it keep clothes dry and drinks cold at the same time?+
A patented internal liner separates the cold compartment from dry storage. The Dual-Mode Shelf™ lets you decide how much space each one gets.
How durable is it?+
Built to take a beating at just over 3 lbs — roughly half the weight of a well-known backpack cooler. Backed by a lifetime warranty against defects in materials or craftsmanship.
What if it isn't right for me?+
Try it for 100 days. If it isn't right, send it back for a full refund — no forms, no hoops. We've offered this since day one.
