I have knee problems that run in the family. I bought these to try to help knee pain after cycling and they work pretty well. Easy to get on, fairly comfortable, and they are the perfect amount of cold. Typically I find that packs like these are either not cold at all or Im worried Im getting frostbite... these are in the goldilocks zone, at least for me and they stay cold for quite awhile. They Do help with recovery.

I needed a way to ice both knees after a reaction. Compared to putting on an ice pack and trying to hold it while winding an ACE bandage around it (3 hand problem), this was orders of magnitude better. Not only does it go on fast, but it also sorta stays put if you need to move around. The biggest negative is that the edges of the ice pack are kinda sharp (seam welded plastic sheeting) and depending on how the pad sits, the edge can dig into your skin on the low (foot) side of the pad. I find I can manipulate it a bit to pull the seam away, but largely it is a mental process to ignore. They can also slip down, but that usually just means you need to tighten the straps. Mobility is not great as you have to walk stick-legged, but compared to alternatives, it is great. As others have noted, the fuzzy side doesnt feel as cold as the smooth side. I find I can start on the fuzzy side and then flip around for the colder side once the shock of putting it on is over. If they could solve the sharp edge issue, these would be 100%. But even with it, give these serious consideration if you want a fast, reliable, hands-free way to ice knees.

Two sides are a nice option. The side with fabric is so soft and feels wonderful.

Just had knee surgery and wanted a good easy way to ice the knee in recovery. These work great. I bought two because I need to uses frequently. Freeze time is min two hours after used for effectiveness but first time freeze overnight. It says four hours and that probably works too.

My boyfriend loves this ice pack for his bad knee

Got this for my mother after her knee surgery and she loves it.

I ice my bad knee after exercise. It works well. I like the soft side can be used as well as the really cold side

Stays in place

I really like the comfortable feel of this ice bag and the way it can conform to your knee. I’ve probably have had a half dozen of these types of ice bags for my knees over the years, but this one is the best.

Bought 2. Using for the knee replacement, wraps easy around knee stays cold.
