Multipurpose piece of kit
Fitted without being restrictive. Moves with you and doesn't flap. With a midweight baselayer (Craft Zero) it is great from the mid 40 to mid 50 degrees F. Enough perspiration evaporates during hard efforts that you avoid moisture buildup and the subsequent chill once the effort ends. Haven't yet used it in the rain. Only had the pleasure of keeping my backside dry on wet roads.
Only knocks are the construction creates squared shoulders - reminds me of a Michael Jackson "thriller" jacket shoulders. The vents are of little utility - not much difference between open or closed. Small knocks against an otherwise excellent piece.
I plan to pair with the new Assos rain knickers on foul weather rides.
