Everlasting Ice RX Reusable Ice Packs for Cooler (4 Pack) Up to 48 Hours Freezer Packs for Coolers and Lunch Boxes | 10 x 10 in | Cooler Ice Packs for Camping, Fishing, Beach, Road Trips

These ice packs really work. They are super easy to use – you just add water, it mixes with whatever substance is already inside the bags, and turns into gel-like mass. You freeze it for about 24 hours and you can use it, and reuse it over and over again. They keep the cold really good – I left raw meat in the cooler with two of those ice packs for half a day in a hot California car while we were driving to our camping location, and the meat actually stayed cold. Definitely recommend!

We just received these and used them for the first time. They worked great and stayed frozen for a 10 hour drive. Easy to initially fill and freeze.

These stay cold for long amounts of time. They also freeze quickly when put in the freezer. Very easy to pack in my lunch box.

Works good and stays cold for hours

It keeps your food cold when you buy a good lunch box. My food stay cold for about a day and a half.

These actually stay cold! Skeptical living in the hottest place in the US, but they lasted over 48 hours in a cooler in a hot car.

They work very well, but I ordered the Cooler Ice Packs and they sent me the Lunchbox Ice Packs. I didn't realize it till I used them the first time.

I loved this. It kept everything cold for days and I have re-used it again and again!
