My 62 year old knees have pain at the top of my patella if my knees are cool. I use knee warmers and/or tights when it is cold with good results but for temps between 60 and 70 F they are too warm.

I've been looking for a thin knee covering for a long time and just saw the copper knee compression sleeves promoted by Brett Favre in a store and they are a nice thin weight.

I'm wondering if anyone has used those or similar products and if they are too constricting or bunch up when cycling. I've tried other elastic braces and eventually they bind in the back of the knee are are uncomfortable.

I'd appreciate any input or recommendations on these copper sleeves.
