I usually wear these when the temperature is below 40 degrees, but one day the temp went up to 60 when I had these on earlier in the day when it was colder and interestingly enough, I was not over heated. They do a great job of keeping the wind from blowing right "through" me and it's very comfortable to wear these at work. They don't "stick" to your legs, they have a very relaxed fit. I thought the price was a little high but this is a good quality product so I won't complain. I bought two pair, white and dark navy, for every occasion! ;-)
