Excellent design and quality
I've tried a lot of different brands. I hike take moderate hikes regularly, have moderate arthritis, am old.(73) These are thin, yet provide the right amount of support- not too much which for me can actually increase pain due to lack smooth interaction between all areas of the knee. They are very durable. Worth the price!

AMAZING SUPPORT......HIGHLY RECOMMEND
Was a bit hesitant when ordering these. You never know what you are going to get with these and everyone is shaped so differently. But was so pleasantly surprised. LOVE them. I was preparing for a 2wk European British Isle tour.......LOTS of walking. I wanted something that would be great support without causing irritation. Just a nice support. I searched for 2 weeks and poured over reviews. And settled on these. I ordered for both knees so I would have support for both even though I technically only have 1 bad knee. I am so glad I did. They worked great!!! 2 years ago, I did a Tour of Italy and ordered a neoprene one for just the bad knee. That brace was like walking through hell. It was thick, bulky and not breathable causing irritation and blisters. I didn't want to repeat that again. I am now back from my tour and so glad I took these. I wore them daily....even on the airplane in place of my compression socks. My knees never gave way, didn't have the severe pain I was expecting......it was a nice trip all due to having the support I needed. Since getting home, I haven't worn them and I honestly kinda miss them. I didn't realize how much a little support goes a long way. I didn't realize how much support they provided to my weak knee until I stopped wearing them. So needless to say, even though I am home, when I go out......yep, I am wearing it. I really liked the placement of the anti-slip grips on the inside of the braces. I was concerned with irritation but never had an issue with that. There are anti-slip grips around the knee and along the upper and lower bands. Some customers mentioned slippage. Please note.....when you pull the brace on, the upper and lower bands have to be completed flat against the leg or you will have slippage. It created almost like seal of sorts. The few times I had issues with slippage, I could see that the upper band around the thigh had a spot that wasn't flat against the skin. Once corrected, slippage wasn't a problem. I also highly recommend ordering a size up. Had I gone with the recommended size, they would have never worked. Some customers also mentioned seams coming apart. I did notice that the seams in the back of the brace starting to separate. But I also noticed it is separating from being pulling on from the top of the brace. Now I pull it on with the sides collected together instead of just pulling from the top. I highly recommend these braces and will definitely be repurchasing them.

Very supportive brace
This knee brace is very supportive and easy to put on/off. The only reason I didn't give it 5 stars is because the top band feels quite tight after awhile so I need to remove it.

Best Knee Braces
I love these braces. I have four of them, and two have lasted over five years. They’re fantastic for knee stability or relieving a pinched fat pad. They’re lightweight and thin as well, making them perfect to wear under clothes or while traveling. I recommend washing them in a laundry bag and letting them air dry — that’s how mine have stayed in great shape for so long.

Exceeded expectations- UPDATE spoke too fast
I have been using a compression sleeve for my knee for about 5 yrs now due to ACL reconstruction and meniscus damage in my early 20s. I have been satisfied with the more popular sleeve sold here on Amazon - Modvel brand sleeve. I was looking for something a little less bulky and more friendly to wear under clothing. This sleeve exceeded my expectation. You can actually feel the graduated compression. I feel even more supported with this compression sleeve and it's way less bulky. I'm sold and will continue to use this sleeve. I'll update when I have a few months in to see if it holds up with the compression. It really helps me and hopefully, it helps you too! UPDATE**** Welp, I spoke too soon. Starting to rip with just barely a month over since purchase. I'm outside of the return window by 3 days. See pictures of how it is ripping at the kneecap area. Was only using 3 times a week for 3 hours a day for physical therapy. Very disappointed. I hadn't even washed it yet.

A knee sleeve that *actually* stays put and stabilizes
The headline says it all-- this is one of the few knee sleeves out there that actually stays in position while providing stability and relief. I do a lot of distance running, and this is the first sleeve that I haven't had to stop using due to having to hike back up into position (all other knee sleeves I've used quickly drift down on the upper part above the knee, and won't hold on.) It doesn't cut off circulation (I have large thighs, and would notice) and is very comfortable. My particular issue revolves around a loose ligament inside/under my knee that is sometimes very painful, and I also struggle with the ability to do deep knee bends or jumps (getting older.) With this on, the issues are about only 10% of what they were, if at all! I feel like I have the knee I remember in my mid/late 20s again. Before leaving my review, I wanted to wait a couple months and make sure that the sleeve would remain in good shape. After a lot of running in it. the sleeve continues to stay put on my knee during use. In my experience, this truly is a 5-star product, and I'm going to buy another for use during the day when I'm not running (handwashing can only remove so many weeks and months of sweat.) My parents and siblings already know about this brand, and I'll tell anyone about this sleeve if the subject comes up. It's worth buying, 100%

Can resume normal activities.
Great product!!! Enabled me too get around again without fear of my knee “going out”. I would definitely purchase this again. I was thinking about knee replacement, but maybe I won’t have to.

Doesn't last
This is great for awhile, though after a few months it starts to loose its compression and breaks appear in the fabric

Me esta ayudando a poder caminar, me quedo perfecta con la talla que elegi, realmente increible soporte en la rodilla, me ayuda a sentirme comodo y seguro sin lastimarme al caminar, sentarme, es una rodillera perfecta para las personas que han tenido cirugias o heridas en la rodilla y sentirse seguro y comodo. Realmente muy buena y recomendada.

No size chart. I ordered a large and it's too small. Aggravation and time wasted along with paying for something that doesn't fit.

Performance is excellent

Fantastic product. I went to a physio who recommended this product specifically. I was doubtful as I've had constant knee issues whenever I've tried to increase speed or run over 5 miles. Since wearing it I've been both pain and discomfort free. Couldn't recommended higher.

Fui intervenida de artroscopia por daño a menisco medial. Después de la rehabilitación pude regresar al ejercicio con ayuda de la rodillera. 1000% recomendada ya pedí el par.
