Polar Tech TP32/MS Ice Brix Viscous Gel Moisture Safe Refrigerant Cold Pack, 10" Length x 6" Width x 1-1/2" Thick (Case of 9)

I love these ice bricks! I was given one of these by my vet to transport medicine home for my kitten. I had broken my ankles two weeks prior and decided to try to re-use it to help with the immense swelling I was experiencing. Holy cow, it was a god send. Even in the middle of the summer it stayed frozen rock solid for hours, up to eight! After nearly two years of use I stepped on it accidentally and it exploded, so off I went in search of more.On a whim I looked on Amazon and lo and behold here they were. Not just one ice pack but an entire box full, for less than one therapeutic pack costs at the local megamart! My packs arrived perfectly packaged and just as their predecessor, freeze beautifully. Rock solid, icy cool comfort for hours. I've even had one last up to 16 hours in cooler weather! These are sturdy and my go-to packs, i use two daily.

Stay cool a long time although weirdly it seems like the smaller ones might stay cool slightly longer. .maybe its the flocked cover...Both styles are sooo much better than dumb store ones...the big ones partially frozen would be GREAT for the body or neck with the length and soft cover..as well as nice to not have to use so many in a cooler..My husband has loooong 16+hr days and the lunchbag ( we prefer the coleman soft an coolers to a reg bag..sturdier and roomier)..doesnt always get indoors..this brand is actually still cool and sometimes partially frozen when he gets home unlike store ones which are totally warm at end of day..We us the 18can cooler ( kinda big but fits containers better and has a sturdy shoulder strap)And I use 1 large and 2-3 of the smaller ones..its been mid 80s + ..when august I'll see if i need to add more..they do get heavy but no way around that..Also when you stack em in freezer they expand more than you think so don't stack too high lol..

We use these as “air conditioning” in the feral rehab colony’s catio. Placed in protective covers, they are quite resistant to claws.They hold a “chill” for several hours once frozen solid. Perfect size to tuck into condos, too.Unfortunately, two in this order were ruptured along the seam upon delivery. The box was slightly damp & sticky on the inside. Most of the gel had solidified in the box, although the two paks were still leaking.Will definitely reorder. They make hazy, hot, & humid days more “komfetable for kitties”.

Upon receiving I paced 4 packs in the freezer and left the other 5 in the box. A month later I was going to use the other packs and found 2 were leaking, 1 is missing and its past the time to return.

I really like these. They don't leak easily. It takes A LOT of weight sitting on these to make them leak. The only time we have had one actually leak was after someone accidentally sat on it. That person weighed over 200 pounds. These really do hold up well. They keep things good and cold. They stay good and frozen for 6 to 8 hours.

they freeze but dont hold cold as well as the plastic packages of brix and the STICK to my freezer or anything in it! I had to pry 3 off with a frickin crow bar then started using parcment bt them. lotta maintenance for some cold packs.

So much better and so much less expensive than the ice packs sold for home/lunchbox use! The cloth-like cover doesn't get slick with condensation and it's much less likely to burst or leak than the kind with the plastic cover. And, they're thick, so they stay cold forever; in a use case where the Wal-Mart cooler ice packs are always completely melted and slightly warm at the end of the day, these are still cold and still have a chunk of frozen gel in the middle. And you get so many of them! They're the best. Thanks, Polar Tech, for making these available to average consumers.

These are amazing! I live in south Florida and we bought these in order to leave our lunch bag in the hot car until lunch time. Previously we used the hard plastic ones you can buy at the supermarket but they kept warping and cracking. These soft ones work much better. 3 of them keep our lunches ice cold and are even still frozen at the end of the day. They're super durable and the flocked outside keeps them from sticking to each other or the freezer. These were exactly what we were looking for and better than our expectations.
