5 Rules for Packing a Cooler That Actually Stays Cold

Pre-chill everything before it goes in Warm drinks and food melt ice fast, wasting space before you even start. Cold items stay cold longer.

Use block ice instead of cubes Cubes melt into slush that takes up space. Blocks last longer and let you stack drinks directly on top.

Fill every gap with frozen water bottles or sealed ice bags Dead space is wasted cooling power. These act as both coolant and filler.

Organize by weight and risk Heavy drinks on bottom, food on top. Keep raw meat sealed in a leakproof container on the very bottom in case of drips.

Stuff remaining gaps with a towel or newspaper It insulates and prevents rattling. A well-packed cooler should have zero empty air pockets.
