Cryomax Med Cold Pack Medium, 1 ea

Love the big size it covers larger pain areas , stays cold for long time, personally I don't wrap it to attach around my back. I have but I like laying flat on my bed using it on my back. As far as ice packs go and I have had so many different types. I have to honestly say, I like this one the best. If you have large area of back pain, this is an item that will give you a lot of comfort and help ease your pain. Totally worth buying.

I was very hesitant to believe that these would work for eight hours. It’s summertime and I live in Hawaii. Ice packs seem to only last for 20 or 30 minutes around here. A couple days ago on the hottest day we’ve had in a long time, I brought my 2 ice packs with me as I had injured my back. I originally bought two so that I could wrap them around my arms after Allergy Shots to help with the swelling. Anyways, I started around 9 am , I ran around doing errands with it on my back. Around 1 o’clock, I was going to an event in the park and did not want to bring it. I had brought one additional old-school hard ice pack as well with me (Read the directions to see why). It has been inside a cooler. (and was not super cold anymore) I put the 2CRYOMAX ice packs on top of each other with the hard one in the pile as well. I took my sunshade for the windshield and laid it over the ice packs that were on my seat. The windows were up, and the car was in the sun with no other shades. It was crazy hot that day. I came back around 5 PM and absolutely positively could not believe that the CRYOMAX ice packs were still cold. I honestly was not expecting that, I had already been impressed. I don’t mean, cool, they were cold! Definitely read the directions and make sure they are frozen solid before you use them if possible. The liquid won’t freeze the same way the little balls will. I am beyond impressed with this product and have already shared it with the injection center at my hospital. The only two things that I would want to see changed would be the color of the liquid, if it were to leak, in my opinion, that color would be likely to stain. The other thing I would like to see them change is having the flexible plastic CYROMAX Pac, feel more durable. Don’t get me wrong, my gut tells me that it is extremely durable… It’s more of a psychological thing I think. I will update if there are any problems. Super impressed!!!! There are some reviews that say that it does not say cold. I think the problem is that they are not letting the balls freeze solid first. Additionally, I have noticed that once my arms are numb from cold, it often feels like any ice pack I’m using is no longer cold, but if I take the ice pack and put it against a different part of my body, I realize it still is very cold and that I was just numb to it. Perhaps some users have had that happen. I’m not affiliated and I have not been paid or given anything free or whatever it is companies do to sometimes get reviews. Even if these only work half as good as they did that day from now on, they’re still incredible! I’m just a super happy customer!

Great Stays cold Great size

These ice packs are AMAZING (will explain the Subscribe & Save caveat). I have chronic pain so I have 2 sets of the ice packs I need that are in a constant rotation. Why you need it: * Once fully frozen, it really does last up to 8 hours. I easily get 6 and usually the full 8. I'm sure the conditions and amount of insulation being used affect this. * You won't find any other kind that stays colder or for longer- I have tried them all, trust me. * The covers they come with are excellent insulators (which you will NEED). The straps are also super helpful for various situations since the strong velcro can stick to any part of the cover. Wrap around any size limb, or use to wrap around/ attach to stuff (I use them to hang the ice pack against the back of my wheelchair for back pain). * Even if only partially frozen, can get a lot of use out of them * The bumps are not uncomfortable * There are some easy work-arounds to some of the problems Tricky things to know/ keep in mind: * They take a long time to get fully frozen, and freeze best with air space in the freezer. I've found it takes 3-4 hours to get completely frozen. The blue bubbles will freeze hard first, then the pink liquid "matrix" will freeze last, and that's where the magic is, you need that pink stuff for it to last longest. * It's not that moldable when fully frozen, but if you use it when the pink isn't completely frozen yet, then it will bend more, along the gaps between blue bubbles. * There's a reason they're offered on "Subscribe & Save"! The pink stuff will eventually leak out (and get stuff wet), and with continued use some of the blue dots will also pop and leak out. Without the pink matrix, you can still use it with just the dots, but it's not nearly as long-lasting (freezes faster though). So with constant daily use like me, you'll need to replace them after about 4-6 months. (I don't recommend actually getting on S&S, just replace as needed.) Work-around: Always keep these in a 2-gallon ziplock bag! Doing this has extended the life greatly, and prevents the liquid getting on things when they do leak. (You might need to replace the bags once in a while but that's better than losing the liquid.) I also duct-taped around the edges of a couple of my ice packs, but it's unclear if this has made much difference, I can't tell where exactly the liquid gets out. The bags are most important. Pics- 1) a fully frozen one I've been using for about 6 months, in a ziploc bag. One or 2 blue dots have popped but nothing leaking, so it's fully functional 2) A thawed and "dying" ice pack- several blue bubbles have popped, the pink has begun to leak out (my bag is worn out too), I will have to replace this one soon to get 8-hours of function per use 3) This is a frozen but completely leaked out one, the pink is gone (I didn't have this in a bag!), I can still use it for some things with just the frozen bubbles, and it is flexible but will thaw a lot more quickly. (Side note- the 6x12 don't last as long as the 12x12.) The bottom line/ TL,DR: these are definitely worth it despite the leaking requiring you to replace them periodically. They're the best and only solution for nearly all-day use for chronic pain and/or taking on a day out.

I have been buying these ice packs for years and I use two a night in intervals. It helps to keep me cool, which helps me ward off migraines. I sleep on one wrapped in a towel and stick it on top of my pillow. When it has melted to room temperature, it usually wakes me up and I go out and switch it with the backup in the freezer. The size is perfect for neck and head, quality is pretty good and the design is well thought up. It even comes with its own cover so you don’t need a towel for the most part. I just use one for extra cushion and so it doesn’t freeze my skull and brains, lol. If you don’t put them away flat and with care, the outside gel water will leak and then you can still use it as the balls stay intact and frozen but they will then only last about 90 minutes. I recommend these ice packs to anyone who suffers with migraines or vertigo.

A GOOD ITEM AT A REASONABLE PRICE. ARRIVED ON TIME. Thank you.

Like other reviewers would agree 8 hours is a stretch but lasted at least 4 hours before I had enough relief that I stopped truly checking. And this was with sustained contact with my body, not just on and off cycles. Around 6 hours later went to put away and was still cold-ish but as I wasn't using it on my body at that point can't truly confirm whether it was "ice worthy". Still much better than previous alternatives and sleeve was comfortable enough for use. Still needed another layer on arm as was too cold for my purposes of extended relief.

It does work better than a flat gel pack as it bends to the required shape and works as a 'cold' pack for hours rather than minutes without frostbite issues- not entirely sure about the 8 hour claim but remains useable for much longer than powder based packs or real ice

Yet to try. Happy it is made in India.

False advertising, and very poor product. Same as every other 1$ coldpacks. Stays cold about 1.5hrs. and package says "to stay cold for 8hrs, product needs to be tr-freezed on freezer every 2 hours for 30min 😂
