So far I've wore them for jogging with weather from 0C to about 15C, these are warm but very breathable, which also makes them great for a 2nd layer on my trips to the mountains. I was afraid it was too big for me as I only buy on Amazon when I travel to the states and return is not an option for me, but sizing is very accurate. Btw I have the Slate Grey color and it looks great with about any outfit.

I'm surprised to see there aren't any reviews on this pants, I'd buy them again if something happened to mine.
