Arctic Ice Tundra Series Long Lasting Reusable Ice Pack - 5° Fahrenheit Cooling Point - Designed to Maintain Freezer-Like Temperatures in Coolers

These Arctic Tundra Series freezer packs have been fantastic. They kept my frozen food frozen during a cross-country road trip using only a mid-priced cooler ($65–$75), which really impressed me. I also used one on a trail ride, and when we stopped for lunch, the water bottles—started at room temperature—had actually begun to freeze. That says a lot about how cold and consistent these packs stay. They’re made from high-quality plastic that’s durable and easy to clean when not frozen. The integrated handle is a great touch and makes them easy to move and position in a cooler. One tip: if you store these at room temperature, be sure to put them in the freezer a few days in advance and set your freezer colder than usual. These packs are dense and take some time to fully freeze—but once they do, they perform extremely well. They’ve worked perfectly for my needs. I currently own three XL (5 lb) packs and four L (2.5 lb) packs and will continue to buy more as needed. It’s really nice not having to stop for ice every day. Highly recommend.

These really do keep things cold forever and will even freeze our drinks. Perfect size for our cooler and stays cold forever. Will keep things cold in my cooler at the beach without issue. We have multiple sizes and pick the ice pack depending on activity. No assembly required.

I bought these ice packs for a long road trip because I didn’t want to deal with melting ice and soggy food. These packs exceeded expectations – they kept our food and drinks cold for the entire 12-hour trip. One important tip: for the best performance, freeze them in a sub-zero freezer if possible. In a standard freezer, the liquid inside doesn’t fully freeze, although the packs still work. However, when frozen in a sub-zero freezer, they become completely solid and last noticeably longer. Highly recommend these for anyone needing dependable cold storage without the mess of traditional ice.

It thaws out the fastest of all my other ice packs. Ill put 3 or 4 in an ice chest to transfer food on long drives. This particular one is always the first to thaw out. I wish I never purchased it

Super expensive, but they work well for keeping my stuff cold while traveling. They do take a long time to freeze, and I've had better luck if I tuck them in the chest freezer. It will take days if I place in standing freezer.

These helped me to transport frozen food during a 9-hour trip. The food remained completely frozen, although the ice packs were partially melted. Some side notes: 1. I was flying and had hoped to bring my small cooler as a carry-on, but the ice packs were partially liquid within 2 hours - not enough time to get from my home to the airport and through security - and therefore could not be carried on. It was no problem as checked luggage. 2. The freezing point of the ice packs is much lower than water, so your freezer needs to be cold enough to freeze them completely. Also, for the same reason, the ice packs are still very cold when the liquid starts to melt. 3. How long the ice packs (and your food) will stay frozen obviously varies depending on your cooler, contents, and travel time.

They stay cold - but you have to freeze them for a few days before first usage. Anyone saying it doesn't last more than 12 hours is user error. I use one in my Yeti Hopper 18 - kept my lunch and leftovers cold all day. Packed 2 for a 8 hour road trip and the cooler (another Yeti) sat overnight in my car and half way through the next day in 90 degree weather, and it was still frozen. The type of coole ryou use matters

Disappointed. What the item description does not tell you is the instructions on the reverse side..."place in freezer for 36 hours at coldest setting". So not useful for daily work cooler.

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.

After more than 10 days in the freezer at -16 degrees celsius the cooling elements are still not fully frozen Are these faulty??

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

My second order. Very effective in keeping items cold for a much longer period of time !

Dice "Pack" y solo viene UNO. No lo hubiera comprado de haber sabido que solo es UNO.
