I am a Male 5'6" 140lbs final purchase medium. I was very skeptical regards the quality and softness when purchased these pants. But I'm glad I purchased them. They just want what I was looking for. A pair of joggers that are loose and relaxed fit but have a nice taper and look stylish. I originally had the small and they fit great and they were snug in the right places. However, I was wanting something with a bit of freedom and looseness as was going to use them mostly when I am around the house and went with a medium instead. The fleece is nice and soft the right amount of thickness that does not overheat you. No shrinkage after washing in cold water and air dry.
