Ice Packs for Coolers, 4 Pack Reusable Long Lasting Freezer Packs for Lunch Bags/Boxes, Cooler Backpack, Camping, Beach, Picnics, Fishing and More, Blue

Freeze well, stay cold over a day. Handy to poke in the gaps where gel blocks won't fit. And good for standing upright so the cold is distributed top down. Best frozen flat so gel freezes evenly.

Very compact and stays cold even when it becomes fluid

Very good. Maintains cold temperatures for hours.

I must first mention it’s built pretty solid and can see having this for long term use, the only downside is that it melts rather quickly, lasting probably less than four hours. By two hours more than half was already liquid, and the drinks were already cold when I put them in. It did keep my drinks ice cold until I got my cooler to the fridge though so that was certainly a win however I’ve had ice packs last for six hours and still be 80% frozen. Those are far too large though and cost $20 each. For my needs it works perfectly. I don’t have enough room in my cooler for the 4x6 ice packs. In the picture shown I actually still fit another 19oz tallboy. These help fit an already crammed drink bag. Black bottle: 28oz, Blender bottle: 42oz, 16 oz monster,
