Not great but inexpensive
This is very thin material and very long so it's not exactly what I was hoping to get but it was relatively cheap as a lightning deal. If you need a lot of support to keep your knee from twisting, this is not for you. If you want some slight support and something to hold in some body heat, you might like this item. I would not order it again. I can't tell that it has any copper infused.
