Love all the technical design aspects of the trousers but there is a design flaw. The label on the inside of the trousers at the front has a sharp edge which digs into your leg by the groin. I get around this by wearing shorts under the trousers. Would love to wear just the trousers with pants but too uncomfortable. They are also quite short in the rise but seem to stay put.
If the label wasn't there, would have given 4 stars.
I'm a sprinter but use these for warm up and winter training.
