You’re not looking for just a cooler.
You’re looking for one bag that actually keeps up.
At Sunjammers, we carry the full lineup of JustinCASE Convertible Backpack Coolers—designed for real life in and out of Panama City.
Beach days. Fishing trips. Travel. Theme parks.
One bag. Zero switching.
Because when your gear works, your day gets easier.
If you’ve ever packed for a day out, you know the problem.
One bag for drinks.
Another for snacks.
Something else for dry gear.
Before you even leave, you’re already carrying too much.
That’s exactly why the JustinCASE Convertible Backpack Cooler was built—to simplify everything.
It’s a cooler + backpack in one, with smart storage that keeps cold items separate from your everyday essentials. No more digging. No more juggling bags. Just one setup that works wherever you go.
🧊 How People Actually Use It
🏖️ Beach Days in Panama City
Heading out to Panama City Beach?
Throw it on your back, walk the sand hands-free, and stay longer because everything you need is already packed right.
🎣 Fishing Trips
From St. Andrews to the flats, this is a go-to setup:
No more stepping around multiple bags in the boat. Everything stays organized and easy to grab.
🎢 Disney & Travel Days
Long days require smart packing.
One bag. All day. No complaints.
🚤 Boat Days & Sandbars
Throw it in the boat, grab it when you anchor—done.
🔥 Why JustinCASE Backpack Coolers Stand Out
📍 Shop Local or Ship Nationwide
If you’re in Panama City, stop by Sunjammers in Historic St. Andrews and check them out in person—we’ll help you find the right one for how you actually use it.
Not local? No problem.
We ship nationwide so you can get the same all-in-one setup wherever you are.
