Arctic IceChillin' Brew Series Long Lasting Reusable Ice Pack - Freezes at 28° Fahrenheit - Designed to Keep Beverages Colder Than Ice

Tried this out on the recommendation of a friend.I have not been disappointed. As with all cooler applications, Pre-chilling both the cooler and the contents is paramount for optimal performance.While the Arctic-Ice literature states that you can use it to completely replace the need for standard ice, I have found that for beer cooler/tailgating type use this does not work well. That said, what it does do is virtually eliminate ice melt within the cooler up until the phase change has completely occurred. I put 2-4 2.5lb panels in my K2 20 quart, along with ice and beer, and in my 65 quart Yeti use 2-3 of the 5 lb panels, plus ice and beer. Without having some ice in the cooler, there is too much airspace, which gets filled with warm air each time you open the cooler. This causes the panels to change phase more quickly than desired, and the beer to be slightly warmer than optimal. By using a combination of ice and Chillin Brew panels, you can achieve good ice to beer contact, with a minimum of air space. This will give you very cold beer, and good solid ice for 1 1/2 - 2 days, even with getting in and out of the cooler constantly. This works very well for me, as we typically spend all weekend on the lake, and I virtually never have to add ice to the cooler throughout the weekend.Alternately, if you are looking to pack food for a vacation, camping trip, etc, there is no need for ice, as you won't be getting in and out of the cooler. For this application I really like the panels much better than ice, because you don't end up with a watery mess. One trick I like to do is to put any raw meet in the bottom of the cooler (in plastic bags of course), then put a Arctic Ice panel laying flat on top of it, and put my other fresh items in the top (Fresh items also in plastic bags for safety). If you do happen to end up with a slight leak, the panels are dishwasher safe, making cleanup a breeze.I don't typically try to transport frozen items that absolutely need to stay frozen, nor do I care if my fresh items such as carrots, celery, get a bit frosty. For this reason I find the Chillin' Brew version of the panels to be the only variety of Arctic-Ice that I need. That said, if you want to strictly handle frozen items, or refrigerator temp items, you may want to look at either the Tundra series or Alaskan series.

I love this ice pack. It remained frozen for many hours. I used it in a soft sided, freezable cooler as an extra ice pack. It made it through 6 hours and helped to keep all items in cooler frozen. It’s thin enough to not take up too much room in cooler. Froze well and quickly. It seems super durable, but I guess time will tell!

perfect fit in my RTIC 45 cooler.

Not the size I wanted to order, even though its smaller it works really good. They are more expensive than id like but they are good.

These ice packs are the best. No bulging sides and the variety of sizes fit in coolers nicely. I throw on in my cooler bag when I grocery shop. Ice cream makes it home in the heat.

i have XL/LG/SM of these products; saves on ice and ease of use. You may or may not recoup costs of ice vs. cost of arctic ice; but you will gain convenience of having dedicated product in your freezer ready to go in a moments notice. There is on caveat that kinda bums me out JUST a BIT and that is the indention of the product if you lay it flat; kinda impossible to have steady drinks on it (if you use it at the bottom of a cooler). There is a multitude of ways you could use these products and they will keep your drinks/products near icicle cold. If you place a drink next to it or ice; do not be surprised if you have a nice 'chunk' that is iced together. Depending on the size of the arctic ice and cooler/bag your using will kinda dictate the 'cool' factor. I have used the 5lb in a Bison/Brute Cooler and have gotten 32 degrees up until 4 days in controlled environment w/o ice (garage). I've use 2.5 and 1.5 lbs for smaller ice bags and have gotten minimal 12-18 hours easily of gr8 coldness (w/ very lil bit of ice).I do so recommend this version of the arctic series and I do feel they are a good investment, more so in convenience and ease of use versus having to go out of your way for ice sometimes. I like them and intend on buying more as time goes on, recommend all sizes for whatever need you have!

Freezes colder than standard ice, and held up through 5 days of summer travel in a cooler.

I got these(XL) specifically for a Yeti Tundra 65 thinking they’d fit perfectly, and boy was I right. 2 of them fit laying flat in the bottom snug enough that they don’t move around at all and leave enough room for 3 more standing on edge if you really want to go all in on the cold. I use 2 on the bottom with a yeti divider in the middle and maybe 1 more on edge against that.First time out was a 4 day camping trip with a case of “sodas”, food and a bag of ice. On day 3, after frequent use and “soda” reloading, much of the ice had melted, but refroze around the blocks in the bottom. Since then I haven’t bought another bag of ice. I use 2 of these flat in the bottom and a couple(yeti) 2lbs to lay on top and this keeps everything plenty cold for at least 3-4 days, which is about as long as I’m ever out for. Last trip I picked up a 32 can soft cooler and stood 1 up in the middle surrounded by “sodas” and it alone kept things frosty for 2 days with very frequent use and “soda” changes... we seem to go through a lot of soda.Along with a big griddle and a great cooler, these have really upped my camping game. I own camping these days.
