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

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

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!!

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