Such a handy bag!
Jamie
Such a handy bag. We use it for kids sport, road trips and 4WD weekends and it keeps everything cold for hours. I also love that it doesn’t look like a typical cooler bag.

Worth every cent!
Amanda
I honestly wasn't expecting to love this bag as much as I do. We used it on a family weekend away to the Gold Coast and it was a game changer for a day at Dreamworld. It comfortably fit our drinks, snacks and lunch, kept everything cold, while saving us money at the same time! Worth every cent!

Frequently Asked Questions

Is the Original Cooler Backpack only for keeping food and drinks cold?

Not at all. She’s made for any day that involves carrying more than expected. Use her for beach days, picnics, road trips, kids’ activities, weekends away or the everyday dash out the door. The insulated interior is there whenever you need it.



She has a roomy 28L capacity, with space for food, drinks, towels, wet swimmers and the extras a full day tends to collect. The tall interior also allows full-size bottles to stand upright, so you can make better use of the available space.

The Sunza Original uses four layers of insulation to help keep the contents cold while you’re out. For the best results, start with chilled food and drinks and add frozen ice packs before you leave.


Yes. The backpack design and padded shoulder straps help distribute the load while leaving your hands free. As with any bag, comfort will depend on how heavily and evenly she’s packed.


Remove all inserts, wipe the insulated interior with a soft, damp cloth after use, then leave the bag open until completely dry before storing her. For spills, use a small amount of mild detergent and avoid harsh cleaning products.




The Sunza Original qualifies for free tracked shipping within Australia. Orders under $100 have a flat $10 shipping fee.




The heat-sealed internal lining is leakproof, helping contain condensation and small spills inside the bag. The top zip isn’t leakproof, though, so she needs to stay upright and shouldn’t be tipped over or submerged. We recommend using sealed containers and ice packs rather than loose ice.






The Sunza Original measures 43cm high and 20cm deep. She’s 43cm wide across the top and tapers to 28cm wide at the base. She has a 28L capacityand weighs approximately 1kg when empty.
