I use this as a baselayer. Under a LS Jersey 40deg MTB or 55deg road, under a Jacket 30deg MTB 40deg road, under a LS jersey and jacket 20deg MTB 30deg road. Very comfortable and I stay drier with this on. Also looks great with a pair of jeans. I bought one, wore it for a month and bought a second one. 5'8 and 160 and the medium is a good fit for me
