Ice Packs for Coolers, Cooler Freezer Packs, The Coldest Pack at 18 Degrees F. No Ice Needed, Reusable

Brilliant!! I used these packs to keep pumped breast milk cold overnight in a cool bag and in my nappy while out and about. I have also used them to keep a dozen or so bags of breastmilk frozen while travelling. I use 2 of the packs overnight in a cool bag and the breastmilk is ice-cold - cold enough to put straight into the fridge. I use 1 pack in the front zip section of my backpack-style nappy bag that holds 3 bottles of breastmilk. The great thing about these packs here is that they are soft when room temperature so I mould them to fit into the small front compartment and then freeze - normal rigid ice packs don’t usually fit. I have used all 5 in my cool bag to keep my breastmilk bags frozen on 2 trips lasting 3 hours - they were still frozen solid at the end of both trips!! When I first read the info on these packs, I was worried that the breastmilk would freeze if a bottle was in contact with them. Luckily this has not been the case as you can control the amount of cooling with the number of packs. These cool packs have taken away so much of the hassle of expressing and storing breastmilk - one less stressor as a new mum!!

Went to Wales, left for 7am, and put this in a cooler for toddler's milk got back for 7pm and the milk was still cool temperature!! This are really good, especially the bigger packs. They say this lasts for 8 hours, it lasts for 10-12!!

Work well and seemed to stay cool longer than regular ice packs

good for keeping fishing bait cold or frozen for a long period of time when used in a cool box or cool bag.

These are the best cooling packs you will ever get

This is American hype it is no better than the other ice packs but for the price you can't complain

Easy to fill and watertight

It works exceptionally, I am really happy for my purchase. I tried to find the best cost/effectiveness and this was the result, it made me discover that the lunch bags we have has bad insulation. They are exceptionally cold for a minimum of 12 hours (in bad insulation) so I'm excited to use these in coolers for summer camping. Thank you so much for making a great product that's also fun to make! No regrets for this purchase.

Keeps cold for half the stated time Better than ice but bags are not as sturdy as the plastic counterparts

Stay cool for more than 8 hours! Great all day in my kids’ lunch !

These were needed for a smaller cooler for golfing. I love the bigger ones (10 x 10). but too big for smaller coolers. These ones don't keep as cold as the bigger size but I guess that is expected as there is not simply not bigger per square inch. They do keep drinks cooler than ambient outside temperature but not super cold. In the summer I never leave the house without 2 cold drinks and 2 cooler shocks in the cooler. I have not used an ice cube in 2 years now,. All cooler shocks. Makes a huge difference when the cooler tips over in my back seat or trunk. No more mess!

When I ordered these with the "some assembly required", I was prepared to be really irritated that I had to do the work to save them the money. But what I found was, it was actually fun putting it together and I was afraid of potential leaks, but out of the 5 I ordered (lunch size), all have had no issues whatsoever, which is surprising as I am not the IKEA assembly guy at all. I expected it would fail and it didn't.... not one drop spilled. The ONLY reason I gave 4 stars instead of 5 (should really be 4.3 ish) is their claims of 8 hours of "as cold as ice". That may be the case if you are using them at room temp, but I bought them to keep beers cold for a 4-5 hour golf round in 95 degrees and for that, it worked, but was dying after 4 hours and the beer was maybe 40 degrees... I prefer 34-36 degrees. Yes I am a beer prima donna. Skeptical on the 8 hour claim, and that is why I did not give 5 stars. But for what I needed, it worked great!!! Maybe the larger versions were the 8 hour ones. Meh. But these things coming out of a very cold freezer will burn your hands, be very careful! They are so flipping cold! Protect your hands if using a very cold freezer or you may get frostbite. If you doubt the colder than ice claim, put it in a deep freezer and lose a few fingers if you are not careful taking it out... Overall, no issues at all with the lunch size pack of 5. Durable, convenient, and definitely way better than ice, and other non-ice solutions we have used. And for me and my wife the money was well spent for sure. For 5 stars, and this is not just for this product, promise less and deliver a bit more. But this is pretty awesome compared to a lot of other products we have tried. We are considering the larger versions, based on the performance of the smaller items and may update this review based on that. May yet get 5 stars, we will see. 8.8/10 Have recommended to friends and family. Place this in the best triple walled cooler and you may have a cold beer next week... or at least a 40 degree beer....
