I've been having knee pain for the past few months so I decided to try this support brace. I can't believe how much support it does provide and my knee pain has gone down significantly. It's slim so you can wear it under pants while at work but also looks fine with shorts. So glad I found this and it is helping with my knee pain!

Ex Output:
positive

The sweater is really soft and comfortable. The quality is nicer than I expected. It is true to color as well. The size could be a little bigger than I normally wear but then it is loose fitting as described. Overall I am really happy with the purchase.
