Large Ice Packs for Coolers - 13 x 10 x 0.5 inch Freezer Packs - Long-Lasting and Reusable Dry ice, 25 Minute Quick Freeze

Love these! They work great in backpack coolers! They’re just the right size and weight. You can use them in big coolers to making them very versatile. Very clean design. Perfect size of thickness for keeping things cool.

I place on e in th too if my coole and one on the bottom then the drinks in between with a few smaller blue ice packs and it really keeps everything super cold, they work well and don't take him much space

I needed something to keep the cooler cold for about three hours. These are more than sufficient. I don’t know the extent of their capability because I really only need them for that length of time. I like them because they don’t take up a lot of room but they have plenty of surface area to keep things like milk, butter, cheese and yogurt cold for a few hours. I bet they would last five hours, maybe more but I have never tested them so I can’t be sure. Also to be fair, I put a large Ziploc full of ice in each time because I like to have ice at my destination. So likely that helps too.

Fits great in large back pack lunch bag. Easy to freeze every morning. Keeps my sodas n sandwiches very cold in my 10 work shift. Sure to good investment for camp coolers is very skinny n should keep ice longer

I bought these for my Kayak fish catch bag. They work great.

These are a great size nice and slim great for the money and get super cold. Great for all size coolers

I was under the impression from the description these would stay frozen for a long time given the thinness, but they seemed to have thawed quickly, They are a good size for my 60 qt cooler and take up little space. They worked better when I loaded frozen items in the cooler of course. It should be obvious to those who know freezing expands, and lay these flat to freeze, so they dont "bloat"

Love how light and thin these are. They are perfect to take to the grocery store to keep my cold items cold in a cooler.
