Nice jacket, a little thin, but nice
Got this for my wife and it keeps her warm just fine on sub 55-ish degree rides as long as she wears one long sleeve layer underneath. It could also be used as a windbreaker for warmer days. It's thinner than we thought it would be, but very light and does insulate pretty well. She got the small and it's true to her size. The sleeves could have been a little more snug, but there's good room for a base layer or arm warmers if need be.
