From the passenger seat to the trailhead without repacking
A cooler that only works at the destination is dead weight for the whole drive. The JustinCASE earns its seat. It is rugged, it stays put while you are moving, and when you park it goes where wheels do not. A leakproof liner holds up to 30 cans and a bag of ice. Adjustable paracord straps lash a blanket or a wet layer to the outside. And at 3.1 lbs before you load it, carrying it up the trail is the easy part. Van, truck, trail. It does not care which.

The bag that lives in the vehicle
Road trip gear has one extra job: it has to behave while you drive. The JustinCASE is rugged, it stays put while you are moving, and at 3.1 lbs it swings off the seat and onto your back the moment the pavement ends. Cold drinks ride in the leakproof liner, dry layers ride below, and everything leaves the vehicle in one grab.
The first and only convertible backpack
All cooler, all dry storage, or both at the same time. The patent-pending Dual-Mode Shelf is included with every JustinCASE and lets you split the interior however the day demands. No extra gear, no tradeoffs.

Questions, answered
What are the dimensions?+
The 2026 catalog lists the 2nd Gen JustinCASE at 21 inches high, 13.35 inches wide, and 8.35 inches deep. Check your airline's current size and weight limits before flying, including how the bag fits when packed.
How long does it keep ice cold?+
The owner's guide describes 24+ hours of ice retention. For best performance, start with chilled contents and a 2:1 ratio of ice to contents. Actual results depend on packing, outside temperature, and how often you open the cooler.
Can I take it on a plane?+
The JustinCASE is designed for standard overhead bins. Check your airline's size and weight limits before flying, and pack it as dry storage for the trip. Convert it to a cooler when you arrive.
How does it keep clothes dry and drinks cold at the same time?+
A patent-pending internal liner separates the cold compartment from dry storage. Install the Dual-Mode Shelf™ with the JC logo upright: cold drinks and ice go above, up to 11 lbs total, and dry gear goes below.
How durable is it?+
Built to take a beating at just over 3 lbs, easy to carry on daily trips. Backed by a 94.5-year 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.
