Very Trim fit
Love that the entire jacket is 3SP. I have one from years ago but it’s a little large (size M). Purchased mostly because of the note that the jacket will be discontinued with no plans for making it again in the future. Size small fit but was very trim, it did not feel l could wear more than one running type shirt underneath. I live where it gets very cold and generate more wind when I bike, and need more than one layer underneath. Decided to return.
