I ordered the high vis yellow because I don't want the motorist who runs me down from behind claim he didn't see me which is good what's bad about it is that it's hard to keep clean especially if you encounter really grimy conditions so all is good on nice days with clean roads. If it had a black back panel like my vest It would be way better. I'm 5'7" and 150 and the large is nice and snug which it should be, nice stretch to the fabric. It blocks the wind really well and rain beads up on it. It also breaths really well, 0 claminess.
Great jacket for wind, rain, and cool weather protection. I have used it several times with one base layer when temperatures were in the 40s and have been comfortable. And the ability to remove lower sleeves is a big bonus when temperatures rise. Trim fit thru torso and arms.
It is expensive. However, it is flexible. I have worn this with a merino base layer, and regular jersey at around 38F and been comfortable. I have also worn this with a jersey and the vents open at 48F and been comfortable.
The only con I will say is the fit. It is tight in the shoulders and the arms are snug where the sleeves zip on. I was about to return what I ordered which is a medium (I normally wear small so still size up) as it felt overly tight then I got on the bike. In a riding position where it is tight is just right.
