Quick verdict: Purpose-built packs can fit cooler spaces efficiently; frozen drinking-water bottles offer a budget-friendly dual use.
Match outdoor gear to the actual conditions, duration and budget of your trips. The most expensive option is not automatically the best one.
The case for the first option
Reusable gel packs come in flat shapes for food containers, but may cost more and cannot provide drinking water.
Where the alternative wins
Frozen bottles are affordable, reusable and become drinking water as they thaw, though round shapes waste some cooler capacity.
Before you buy
Check leakproof caps, how each fits the cooler, quantity needed and whether cooling can last for the full outing.
Confirm exact product specifications and limitations with the manufacturer, check compatibility and current warranty terms, and consider relevant independent user reports before spending. US and Canadian availability and prices can differ.
Drawbacks and safety
Keep perishable foods at safe temperatures; a cold-looking cooler is not proof of food safety. Use a thermometer when needed.
Who should buy or skip?
Buy the option that addresses a recurring use case. Skip extra features if your existing gear already handles the job safely and reliably.
Final winner
Use frozen bottles for simple short trips; upgrade to flat packs when space and repeated packing matter.
