Cold and dry, at the same time.
Set the shelf in the middle: chilled drinks below, a dry change of clothes above. The patented liner keeps the two worlds apart.
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.
Be the one who shows up ready
Somebody always has the drinks covered when the boat pulls out, and everyone remembers who. The JustinCASE holds up to 30 cans and a bag of ice in a leakproof liner, carries the towels and a dry layer in their own compartment, and lashes the extras to the outside with adjustable paracord straps. When someone asks who thought of all this, that would be you.

Family flights: snacks cold, clothes dry
“Traveling with young kids means snacks are a must. Cold storage up top, dry below — it's become an essential part of how we pack.”

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.
