clammy and does not breathe
This Castelli vest is good for wind and rain protection. However it does a very poor job of transferring heat/sweat to the outside of vest for evaporation. I went on a ride today in cool 50 degree weather and when I took the vest off the inside was dripping wet while the outside was dry. I don't believe it "breathes" as Castelli claims. I have returned it for refund and continue to look for the perfect lightweight wind vest.
