I should have bought two of these! I ride in CA outside of San Francisco where it can be windy and foggy on any given day or you can go over a hill and find a 20 degree temp drop with 15+ mph winds. This bra won't let you down in these conditions. I don't feel hot on warm rides and it certainly does it's job in the wind and cold. Very comfy even after 6 hours in the saddle.
