Love this wind vest. I mostly ride gravel and like a bit of a looser fit. I sized up from my normal cycling sizing and it fits perfect. Not tight and not baggy.
Really nice minimalist vest with a nice cut promoting mobility and aero. Attractive color as well. Nice weight for the tween season(s).
Perfect vest for SF weather, I cannot attest to the packability of it since it breathes so well I haven't taken it off during a ride !! Fits great, zips great, feels great.
