Good lightweight weather proofing
"I originally sized up to large to be able to layer under, but this made the sleeves too long so I returned for medium. This is a nice lightweight fleece lined jacket, lighter than a north face, but more weather resistant and higher quality. It will layer a peloton 200 and 240 of the same size under it, in the same size. With that layering I think you could run this jacket into the 30s, though it would be better stand alone in spring and early fall. Pit zips would make it next level, but that feature is never on these light jackets for some reason."
