Lifoam 4983 The Alaskan Reusable Ice Soft Pack, 14 Ounce

I love these cool-packs. I've been using them for 5+ years in my cooler when I go camping. They seem to stay cold longer than regular ice, without having all that melted ice water slushing around your cooler box. Only downside, once they melt they become useless, and occupy space in your cooler until you re-freeze them again, which is obviously difficult to do on a multi day camping trip. In my cooler, they stay cold for up to three days with outside temps being 80-100 degrees.I've bought my first set of these cool-packs about 6 years ago, and some of them just started to leak. However, 5 years of use for an item this cheap ... I'll take that any day. Final verdict. I would recommend these to my friends, and I'd buy them again.

I have been trying a few different ice pack in my hydration pack I use at work. I can work for 10+ a day in houses with no A/C, in SC, and the water is still cold (plus two bottles of gatorade) with four packs. Theses thing are the best I have used. They are made of plastic and don't stick together in the freezer like other pack I have used do and they really last. I just ordered a second set of 4 today because the days I forget to put them in the freezer at night I can tell the difference when I have to use a bunch of soft packs.Pros:Stays cold a 10+ hours in 80-90 weather (if you have 4 together at least)doesn't stick together in the freezerCons:They are hard packs when frozen so if you let them freeze in the wrong shape they may not fit well.

Bought two of these. One was leaking/punctured. Amazon replaced quickly! Both effective in staying frozen. Used very frequently when out.

These are the longest lasting freezer paks that I have used! The covering could be more durable but my first ones lasted several years. This is a good lunch box size but I use the larger for my coolers.

I took a cross country trip with my cooler and finally had the opportunity to see if these are as good as I have heard....and they are. These stay cold much longer than ice. After an entire 12 hour driving day in the cooler, they were still over 75% frozen. I put them in the freezer at the hotel and went on my way again. When I arrived I emptied my cooler and left them in the empty cooler for a few days. When I went to get them they were gel like again as expected. I pulled them out on to find that unfortunately 3 of the 4 had slimy clear goo coming out of the side seams. There was no damage to them it was along the seam. I cannot believe that for what these cost they are only good for one use. The quality of the seams, glue, or whatever seals the seams is worthless. Of course I am not able to return them because I didn't use them immediately after I bought them, plus they are leaking so they are in the trash now. Highly disappointed with the quality of the packaging, but the product worked great.You can see the Freez Pak on the left is fine. The one on the right you can see the discoloration where it leaked at the seam.

Stays cold for a very, very long time. I put it in a gallon ziplock bag to keep the condensation inside the bag & not on me. I use it on my low back & yes, I know I’m only supposed to use ice packs for 15-20 min at a time. Instead I wrap this cold pack in a pillowcase with a small pillow & prop it against my back. It can seriously last, being still icy in the middle after being up against me all night. I’ve tried other medical gel & other ice packs to only have them last maybe an hour, usually less. Of course this would be great for someone’s ice chest if it lasts this long the way I use it.

These ice packs are a good size. As the other reviewer said, they stay frozen for a long time (about 8 hours for me). I like that they are thin and fit in my lunch box. But, after about 6 months, they started leaking. I really wish they had held up longer.

I have a bad spinal disease & I MUST have ice packs that freeze SOLID/LIKE A BLOCK OF ICE each night. I double these in Ziploc gallon bags (2 per bag) & use them to put under my back. It numbs the pain so I can get at least 2-3 hours of sleep. Even after 8 hours under my back, they’re still hard in the middle & about 50% thawed. I absolutely LOVE these!!
