5. Igloo Ice Pack Backpack 12L - Best for Kids

Its 1‑inch insulated liner holds a single ice pack (included) and can keep snacks cool for up to 8 hours.

At 12 liters and a low price point, it’s ideal for parents who need a simple solution for lunches or beach outings.
How to Choose
When selecting a backpack cooler, start with capacity. A 15‑20 liter pack works well for day hikes, while 25‑30 liters are better for overnight trips that require larger meals and extra water. Insulation thickness is the next key factor; thicker foam or rotomolded walls keep ice longer but add weight. Look for removable liners if you want the flexibility to use the cooler separately or to make cleaning easier.
Fit and comfort are just as important as cooling performance. Adjustable shoulder straps, padded backs and, for heavier loads, a hip belt help distribute weight and reduce fatigue. Finally, consider additional features such as drain valves, external pockets, and compatibility with hydration reservoirs, which can make your outdoor experience smoother.
