I was looking for a knee sleeve that actually fits. I've purchased a few along the way; some were either too tight or just didn't feel right. This (CopperJoint Athletic Knee Sleeve) fits perfect and feels good on my knee area. It has just the right support. I ordered a size up since they come in all sizes. Great sleeve for all activities.
It’s nice, warm and comfortable to wear It done the job for my Right knee It gave it a lot of support When I needed it Itmade it feel a lot better
Works great. Supportive to my knee and was able to bike ride and my knee didn’t hurt. It is a little hot to wear but does the trick. Stays on and doesn’t fall down.
I bought this brace because I messed up my knee when I passed out from illness not too long ago. My knee has been aching ever since and the doctors couldn't find anything medically wrong with it (nothing broken or torn). Being on my feet for 8+ hours a day in my retail job, I needed something to help as it was starting to wear on me. Going up the stairs was painful. Standing up after sitting down was painful. Putting my leg into bed and leaning on it to get in was painful. I knew something needed to help support my knee.At first, I tried one of those cheap $10 ACE braces, but it didn't do much to help. On top of that, even their biggest size was too small for me and would cut off my circulation about an hour into wearing it leaving deep pressure lines on my skin. I didn't want to go full on "Stone Cold Steve Austin" / "I just tore my ACL and want to still play football" $100 braces. So I settled on this after a suggestion from a friend. At $30, I hoped it would do something to help. And it did.The sizing was spot on for me. No lines digging into my legs because its too small. It also didn't keep falling down like other braces (at least not at first) due to the inclusion of a rubbery material near the edges on the inside. It didn't bother me to wear it all day like the other braces I tried (I even accidentally wore it to bed a few times without remembering it was on). And it helped me get through the day. Stairs became significantly less painful to walk up. Standing for hours wasn't a problem anymore. I could even jog on the treadmill again at the gym for a while without much pain.My only problems with this come after using it for several months. The rubbery material on the inside designed to keep the sleeve from rolling down is starting to crack and wear off, resulting in it slipping down a little from time to time. But not nearly as bad as the other braces I tried. Also the logo on the sleeve is wearing off because its screen-printed on and the little yellow flakes keep getting on my pants and showing up in random spots. Other than those very minor problems, I very much like it and find it very helpful.
I've had many knee sleeves over the last 10 years after a Right Meniscectomy and then tore my left meniscus rehabbing the right. I've been wearing these over the last 24 hours and oddly my knees have less pain already. I actually slept in them, as I do have knee pain at night; that speaks to the fit, comfort and support, obviously. I could never have slept in any of the other sleeves I've tried nor, warn them for long periods of time either due to being bulky, uncomfortable. Do be aware if you buy and wear the pair, sometimes one knee is a bit larger than the other normally and from arthritis, along with everyday wear and tear and they will likely feel slightly different, but nothing is wrong: it's your knees, not the sleeves.
