The knit feel of the fabric is nice in cold weather. No cold nylon feel to it. Perfect pant for cold mornings if you like a thin pant. These pants have a relaxed fit. I'm 5'8" 124 lbs. and the Women's Medium is a little more 'relaxed' than I like for running. I'm hoping it allows the pant to be thrown in the dryer. If you like a more streamlined fit order down a size. I usually wear a 31'inseam and the Women's Medium was a good length. I have an old pair that is 10yrs old at least and still going strong.
