Arctic Ice Tundra Series Reusable Cooler Pack

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 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.

so far so good , it lasts very well , but does need 2 days in the freezer to reach max effect for me

I used 2 of these in a Canyon Cooler that is kept in the back of my Outback. I used 1 twenty pound bad of ice. Meat that I wanted to keep frozen was placed on top of these before the ice went in. I also carry a large insulated water container with ice for drinks in this cooler. That ice in the water container remained intact without clumping together or evaporation. On day 5, the ice in the cooler started to melt a little, but remained mostly intact. Internal cooler temperatures ranged from 32 degrees to 45 degrees depending on the heat of the day. FYI, I had a smaller yeti with a smaller Arctic ice pack at the same time. The ice in it melted within 3 days. These are huge and heavy ice packs. They work great on long trips. I would recommend them.
