Cryo-Max Cold Pack, 8 Hour Reusable Cold Therapy Ice Pack for Elbows, Knees, Neck + More, Medium, 6" x 12" (1 Count)

I swear by these cryomax cold packs. I've never had an ice pack that gets as cold as this one does. It really helps my back pain and I bought the larger one to cover a bigger area of my back so now I can ice almost half my back at once. It is somewhat rigid when it's frozen solid but once it's melted a little it's pretty flexible. They honestly don't lie about how long it stays cold for, I think it stays cold for hours if I'm honest. I do a few 20 minutes on 20 minutes off sessions before needing to put it back into the freezer again which is nice because this gets stored in my basement freezer. I have two of the smaller sizes as well that I picked up a 10 years ago and 5 years ago I bought a second one and while the gel stuff isn't quite what it once was they do still work. Now that I have the bigger one I mainly use those for transporting food in coolers to and from our campground because it stays cold forever.

Keeps cold for hours. Coldness lasts much longer than others I have tried. I will order more of these for my migraines as they are the only cold pack that stays cold.

After 10 different other packs on Amazon these are the best I've found. I have bought these so many times over the years. right now I have 5. 3xT shaped and two medium. also two spares un frozen for replacements, The sleeves always go first and are low quality but I also like to tighten them pretty good. Also in general they will leak if you dont follow the directions or get a bad one and they generally will leak after a couple years of weekly use in my experience. They key things is to not flex the plastic when they are right outta of the freezer when the plastic is most brittle to avoid leaks. they say wait 30mins if you read the directions (i did by coincidence years later...lol). and they will still be just as cold just a bit annoying to wait. you can get away with it if you use them flat or you bend them in reverse and dont force them to curve until they thaw a little however. I found out the hard way after trying to use them on my knees I would try to force them to curve right outta the fridge and they would leak. but exact same type on my back would last forever because it was flat, go figure. I also had one had a small hole from shipping i suspect but Amazon replaced it. to be honest i still use em after all the gel liquid leaks out anyway and they still work relatively well with just the "cubes" as they are separated. Im a warm body and the bigger packs last longer obviously but I get about 1h30m mins iced time and another 30 mins cold time. Best time results I've found for years now. Ice feels great to get to sleep but body temp by morning. I'm a big guy and can lay on them cautiously and no issues other than what I've already said. I do wish they offered a 1×4 square long model to wrap all the way around my knee but I make do with two mediums for now.

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 gone through so many ice packs. I really like this once. It's one of the better ice packs. It's like a bunch of tiny ice cubes & stays cold for a long time. Good for injuries or when you just want to cool down.

I have chronic severe pain and over the course of the last few years, have bought about $200 worth of these ice packs because they do stay cold for so long and provided me with pain relief and I would rotate them out throughout the night. I haven't found any other ice packs that stay cold as long as they do. That's for certain. I did sometimes lay on the the larger ones and they withstood that for some time before inevitably leaking. Even the smaller ones would eventually start leaking and I didn't lay on those. They would last a few months of mild daily use. Still not worth the $$ any way you look at it. At the end of the day, I really feel ripped off because I only kept buying these out of desperation for extended pain relief and ended up spending a lot of money; wracking up more medical bills because of them and coming into contact with whatever toxic chemicals are in these packs for my trouble. Some would just leak a small amount and so I kept thinking the moisture was condensation at first until I changed my darker colored sheets to white ones and saw the pink color. Then a couple of them leaked badly--the pink fluid in between the little ice nodes is what leaked out. I know this is a problem that WILL happen eventually to almost everyone just from my own experience and reading other reviewers who have complained about the same thing here. At first I didn't attribute the rash I had across my back to the chemical. I actually went to the doctor and was treated for shingles. I had a horrible itching burning rash across the entire width of my back, rear and hips. After 8 weeks my doctor became really concerned that my rash was not getting better at all and referred me to a dermatologist who immediately told me that it was a severe reaction to something and/or a burn .... not shingles at all! I quickly realized what was causing my severe rash-the pink fluid leaking from the Cryomax ice packs! I don't have allergies nor do I have sensitive skin. This stuff it outright toxic! My dermatologist told me that I had what looked like a chemical burn! Even after I stopped using the ice packs and treated my burns/rash with a topical steroid multiple times a day the "burns" remained angry, burning and itching for a long time. Finally the larger areas of my back started to clear up and heal. The other night I was in so much pain that stupid me decided to use one of the remaining small ice packs on my hip. I thought I had thrown out all the leaky ones. Nope. Here I am again with a horribly painful and itching chemical burn. I fell asleep with the ice pack laying along side my hip and it leaked. Boy am I sorry. I've attached a pic as a warning. Yes these stay very cold for a long time but they WILL leak sooner or later and will cause a chemical burn!!! Even if they don't, whatever chemical is used in them is definitely NOT nontoxic. Another reviewer posted a similar experience of being "burned" by whatever this chemical is. Believe me, it's no joke! I don't know where these things are made but I would say it's not in a country with super strict regulation. I'm certain it isn't the US. If it is, I will report this company. If I get cancer from this I am REALLY going after someone. These ice packs are NOT safe until they replace whatever chemical they are using with something that is safe and nontoxic. Buy at your own risk!

This ice pad is the coldest and longest lasting ice pad on the market, when you first use it do not put it directly on skin. It is so cold that it will burn your skin. You need a thin cloth like a thin shirt between you and the product after 15/20 minutes. I remove the thin shirt and put it directly on my skin for maximum coldness and depth into the tissue/muscles/nerves I have been using them for 20 years they work. They do breakdown if they’re in the freezer too long other words for months on end so once you’re done using it and you know, you may not need it for a while. Remove it from the freezer to preserve the chemicals inside/once you know you’re going to need it once again, then put it back in the freezer.

Works, But Definitely Not 8 Hours I bought the Cryo-Max Cold Pack because it's advertised as providing up to 8 hours of cold therapy, but that wasn't my experience. For me, it stayed noticeably cold for less than 2 hours, and I'd estimate around 2–3 hours at most before it wasn't cold enough to provide the same level of relief. The pack itself is well made, flexible, and easy to use. I like the size because it covers a good area, and it works well when it's actually cold. My main issue is simply the amount of time it stays cold compared with the advertised 8 hours. For shorter cold therapy sessions, it does the job. But if you're buying it specifically because you expect 8 hours of cold, I'd keep your expectations realistic. 3/5 stars — decent cold pack, but the cooling time was much shorter than advertised in my experience

What's not to like... they do exactly what they are meant to do. Everything about them feels quality. I am using them in my cooling vests because they are very flexible and stay cold for hours.

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.
