Happy knee
I purchased one of these locally, and have now purchased a second online. Size matters. Mine fits perfectly - doesn't budge, doesn't bind, and offers just the compression I need to help deal with a knee injury.

Great product. Good support
Great product. Good support. Really light and breathable. I use this when I work. I have a very physical job with alot of walking. This does the job for me. No slip, Grips nicely to your knee and leg with the rubber pieces on the inside. This is my favorite compression sleeve I've had. Works well at the gym while running on the treadmill and elliptical.

Good fit. Definitely do measurements for size chart
Helped reduce pain. Slipped down some, but minimally compared to others I’ve purchased. Worth the purchase for me

My 3rd pair...
These are amazing. Yes, I’m on my 3rd pair, they don’t last forever...I’ve had my ACL replaced twice now and have degenerative arthritis, then also tore my meniscus several times and these provide the greatest amount of relief and pressure on sore knees. They have upgraded the model to be a little longer, which is nice.I’ve tried other brands and they just don’t fit as nice. At $25 a piece, $50 a pair, these are worth every penny.

Well-Made and Very Supportive
This is my second knee brace from OS1st. My leg muscles increased in diameter, so I needed a size larger. Very Satisfied!

Stays in place running or HIIT class!
I am in the gym about 4 days a week. I instruct and take HIIT classes, run trails, and do OCR. Looking for support for my knees that didn't move but allowed my legs to breathe. Read a report on this, tried it side to side with another poly based support (kind that makes your leg sweat). This clearly is superior. I bought a second one for my other leg! Good price point, highly recommend. Been wearing it for a few weeks now. Its supposed to last six months, we'll see.
