Arctic ICE Tundra Series, Long Lasting Reusable Ice Pack, Purple

Thank you so much, I use it for my kids lunch boxes and it keep the fruits fresh Also the lunch box stayed cooled until came back from school ( 8 hours) High recommend for all mums special in 49c hot weather like my country

I use this mostly for beer and drinks in a cooler that I bring to the beach and it works amazingly. Compared to your typical cooler packs built for -2C, it is designed to freeze at -15C meaning you need to make sure your freezer can go down to -17 at least, and keep it there for two to three days to get it to completely freeze. If I don't open up my cooler, the drinks closest will start to freeze. I would advise anyone with food not use this because it will actually freeze your vegetables, for example, tomatoes and cucumbers will actually freeze and not be pleasant. It's for transporting meats or drinks if you are like me and like your drinks super cold.

I've been using this for four months every Saturday and Sunday in a 30 quart Coleman cooler. I work a farmers market from 8am to 5pm in Texas summer heat both days. This keeps my water and whatever I need to keep ice cold, cold. Sometimes I'll throw in a small blue ice pack if I need to use that in another soft sided cooler for fresh veggies. Yesterday morning I had to run and pick up 2 gallons of milk from a farm (2 hour drive) and used the Arctic Ice pack. I forgot to put in the freezer last night and needed to run some errands and pick up some cold items today. It was still cold from yesterday morning and so I left it in the cooler and threw in a small blue ice pack. I left at 9:30 a.m. and it was 1:00 p.m. before I finally got to the store to shop. Even sitting in my hot car while running in and out of other stores, it was still cold enough to put frozen vegetables, ice cream and other refrigerated items in and keep them cold till I got home. The last couple weeks I've moved it to a Coleman Xtreme 70 quart cooler to keep my pastries cooler with our temps hitting 100. Considering I had to open and close it often to remove and replace the pastry containers out to serve customers or get my water, by the end of the day it was still cool inside and still kept my water bottles sitting next to it ice cold. There was no room for a blue ice pack to help out.

I bought three of these for a Lifetime 77 quart cooler (which is an insanely great cooler - way better than a Yeti!), hoping they would keep our food cold for at least 4 or 5 days of our 10 day camping trip. Well, they lasted 9 days before I had to buy ice!! I actually should have only used 2 of these in the cooler, though, because these are incredible! However, it's critically important to properly prepare your food and cooler -- pre-chill or freeze food & drinks ahead of time and pre-chill your cooler for at least a day or two (just throw a couple of bags of ice in your empty cooler). You need to properly pack your cooler, too - Youtube has videos on this. I put some frozen meat on the bottom and it stayed frozen right up until I had to put in ice. This sounds weird, but it was almost inconvenient because I had to remember to take out meat to thaw! I jammed in a container of sour cream nearer to the bottom, right next to one of the ice packs and it froze solid!! I had lunch meat that also froze solid - and it was on the top! Definitely should have just used 2 ice packs and put the third in my drink cooler. The key with these ice packs is to FOLLOW THE INSTRUCTIONS. They need to be put in a freezer that is at -5 degrees, which most kitchen fridge freezers can't get to or can't stay at consistently. These need to go into a deep freezer or they just won't freeze solid. And, these things don't freeze overnight - they need 2-3 days at least (I put them in for a week!). Definitely buying at least one more for me and will be buying these as Christmas gift for my kids that camp!

These keep your food & beverages cold for up to 36 hours longer inside your cooler which is ideal for me as I purchased these for mainly for extended kayak camping trips away without the need for a heavy & bulky electric camp fridge. I'm confident I will get close to 7 days of ice retention now coupled with my IGLOO COOLER. Just make sure you have a decent quality cooler & you're all set! Great product.

After a work colleague told me he'd bought these ice bricks I was sceptical at first given the $ but I know him as a guy who only recommends quality products to me. He was right ! These chillin brew bricks keep drinks (in my case beer cans) amazingly cold like nothing else I've used before.. It's hard to explain how they're kept so cold without them actually being frozen but they do, they're perfect... 2 medium bricks in my 24 Roadie Yeti esky and its the perfect combo. Trust me, spend the extra $ for these quality bricks and you won't be disappointed I'm glad I did. 🥶
