TheraICE Knee Ice Pack Wrap Compression Sleeve for Injuries, Reusable Gel Cold Packs Brace also for Elbow, Ankle & Calf - Flexible Cold Wrap Recovery for Meniscus, ACL, MCL Pain Relief (M)

By far most comfortable I have used. High quality. Great value. Holds the cold!

After cubital tunnel surgery, this has been a godsend. It's super comfortable and fits well. It stays cold and feels good against the skin. Works very well for the price.

I have a couple of these for the head for when I have bad headaches. When I hurt my knee and needed to ice it regularly, I bought one of these. It works as expected and is much easier than dealing with ice or other ice packs and figuring out how to keep it where it needs to be.Pros:Stays in placeLasts a couple of hours after being frozen at least overnightFlexible - you can move around with itFull coverage - it's a sleeve that you stick your leg into and so it covers all around the knee area including the backside as well as ~2 inches above and below the knee.Comes in a reusable bag to store it inCons:Can be too cold. I place a microfiber towel under it to start. After about 15-20 minutes I can remove the towel and still benefit from the coldness for a good 15-20 minutes more.Be sure to look at the sizing chart. I got the medium being 5 foot and 140 lbs., and it's a little snug. However, a size larger may have been too loose. Remember that it's meant to be compression.

I bought the sleeve for a knee injury. I keep it in the freezer (inserted in both plastic bags) and put it on straight from the freezer as it's not too cold for me. It stays cold for about 20 minutes but I keep the sleeve on for a couple of hours beyond that, it makes walking less painful.The medium works for my knee but if I were to buy one for the elbow, I'd buy a smaller size.

I bought them for my daughter & she puts it on immediately after her tennis matches & she doesn’t have to worry about propping it up or holding an ice pack on her knee or moving it around. It slips on nice & tight to get that full cold all around the knee icing. It’s not too tight but stays in place if she needs to move around. It’s helped her pain immensely & you don’t have to worry about any ice melting or getting anything wet.

We have two and they work great for a cold compress. We bought two because as good as they are, they only retain temperature for 15 to 20 minutes. Having the second one allows for a recommended period of application of cold or hot. I would also issue a caution for using hot. Test the hot with hand before putting this on a leg. It can be very painful if to hot from the microwave.

Pro: It is easy; it is convenient; it is comfortable; it is mobile; it is well made.Con: It is not ice. Not even close. The cooling effect lasts 15 minutes tops, ten minutes or less if you slide it on right after a workout when your body is heated.I've been using this on my knee and if it stayed as cold for twenty minutes as it is for the first minute, this would be a great product. But it doesn't. I can feel it warming as every subsequent minute ticks by. When I slip it off after twenty minutes, my knee feels sort of cool, but nothing like after a proper icing.My Conclusion: It is not a replacement for serious ice therapy, but it's a better-than-nothing substitute if ice isn't available, if you need to move around, or if you need a break from the ice cubes, ice bag, and Ace bandage with a good book routine. That said, I haven't yet found a freezer/gel product that mimics the therapeutic effect of real ice; so as gel products go, this is the best I've found.

Nice, comfortable fit that runs true to size.Works well for cold or hot. For hot, 20 secs in the microwave and then in 10 sec increments until you get the temp you want. Be sure to flip it if you are using it in the microwave--don't just microwave one side.
