Reusable Ice Packs for Coolers Long Lasting Cooler Ice Packs for Cooler Bag, Lunch Bags/Box, Cooler Backpacks, Knee Injuries, Back Pain Relief

Great item, so easy to use & the perfect size for my cool box

Highly recommend - Keeps frozen for a long time, I use these a lot while travelling. To help keep things frozen or cold on a long camping trip, I would recommend a bed of ice at the bottom of the cool box then a layer of these then another layer of ice, and these blocks will keep the ice, for days!! Once defrosted re freeze and use again!!

Comes empty with powder and you add water. Used cool box was still cold 72 hours later.

Easy to use and work really well. More then 8 hours in cooler bag

Keeping food cool outside the freezer

This item is defective. I bought this to use for my cold drinks while in hospital. First use and the bag burst at the seams in my cooler bag. Spilling the gel over the contents in the cooler bag. I filled the bags with the correct measurements 28oz even a bit under because I know how ice behaves and didn’t want the product to explode. There are no sharp objects in my bag to cause it to rip. As it was only bottle water bottle juice in the bag. Not happy at all. Where it ripped is the seams of the cover is clearly it’s a product defect

Leaked from the corner next to where the screw cap is, tried the second pack and it did the same. Not sure if I've just been unlucky as these have good reviews. Will be returning and have already ordered some solid blocks.

I've had these a year now and they do not leak, keep things cold and they are super slim so you can put more stuff in the ice chest.

great value. freeze hard, last decent and fit well into coolers

These ice packs were perfect size for our cold backpack of 30L. We had a road trip during the hottest part of summer as well as we have used it on beach - these pack kept cold for more that 24 hours.Our drinks, sandwiches and fruits were cooled during our travels.Best thing to have during summer time.

Perfect for lunches. Stays frozen long time. No chemicals!

These things really work well for keeping things cold in your cooler. I would say these are ice cold, but actually, they are colder than Ice. I’ve put them in my cooler with bottled water, and after a few hours, the bottled water will have ice forming!I love leaving these in my freezer and pulling them out when I need them. They work well when I travel 8 to 10 hours to the beach. They’re still cold when I get there so I throw them in the freezer and the next morning they’re frozen again.They come with whatever freezing chemical they use on the inside. All you have to do is add a certain amount of water and then freeze them. You never have to open them again or replace the water. I had the large size and they worked fine but I wanted some smaller ones for my beach cooler.I definitely recommend giving these a try.
