Review: Good knee support - Gives the right level of support without restriction of movement. Also is comfortable to wear under pants.
Review: 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
*by L***A on October 6, 2025*

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.
