Mine are 4yo and have 6000km plus in them. F1mille. The badge fell off immediately. I wash them in the little string bag they come with in the regular wash and always have.

I have club knicks and other knicks, none compare. The things I most rate are:

NO Rubbing ever anywhere,
Elastic compression is fantastic,
and a the shorter cut (leg length)
