Snacks stay cold. Clothes stay dry. Hands stay free.
Airports with kids are a two-hands job, and so are rest stops. The JustinCASE packs the family run into one bag on your back. Cold storage up top holds the snacks, with a leakproof liner that takes up to 30 cans and a bag of ice. Dry storage below carries the change of clothes you will be glad you brought. The patent-pending Dual-Mode Shelf splits the space however this trip demands, and the whole bag fits overhead bins, so nothing gets surrendered at the gate. You come off the plane with a kid in each hand and everything else on your back.

Snacks up top, dry clothes below, hands free
Traveling with kids means snacks are non-negotiable, and so is a spare change of clothes. The JustinCASE carries both in one bag: cold storage up top, dry below, split however you decide with the patent-pending Dual-Mode Shelf. It fits overhead bins and rides on your back, which leaves both hands where they belong, on your people and the boarding passes.
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.
