Geraldwrote a review of Castelli Espresso Due Jacket on November 30, 2013
Familiarity: I've used it once or twice and have initial impressions
I was looking to put together a kit that would keep me comfortable on those days that drop into the 30's and stay there. I chose the Espresso Due Jacket because of the very good performance I have gotten from Castelli products that use the Wind Stopper material. I have only used the Jacket twice and both times the average temperature was below freezing. Both rides were in the 3 hour range and I felt comfortable the whole time on both rides. The back of the jacket is constructed in a way that leaves a portion of the shoulder seams open. Also, the rear Pockets have mesh vents in them. I assume this is done for ventilation when the jacket is worn in warmer weather than I was riding in. The vents didn't make me cold, but I also wasn't sweating. There are also zippered vents in the front of the jacket. With the right base layer, I am sure this coat would keep you warm into the mid 20's. I paired this Jacket with the Polare Tights and have been very happy so far.
