Good knee support
Gives the right level of support without restriction of movement. Also is comfortable to wear under pants.

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!

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.

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.

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.

Nice but lasts only few months
It has very good compression. Silicon inserts inside patella keep brace in place. There is good breathability. The only concern is durability as it lasts only few months. It is also priced at higher end compared to similar braces on amazon.
