What I meant to say was that I sized up from my usual size of medium in joggers. I don't have a pair of the previous year tech fleece pants. I went off the advice of the store clerk at Nike, she told me that the fit is roomier on this years version and more tts. Despite that after trying on both sizes, she recommended I buy the large; she thought it looked better and less 'megging' like. When I got home I tried the pants on again and feel that they are looser than I wanted. I also noticed that the pants stretch a bit, so what was a good fit initially, is a bit too loose now. Hope that helps...
