ENKwrote a review of Castelli Puro Jersey - Long-Sleeve - Men's on January 28, 2016
Familiarity: I've put it through the wringer
Fit: True to size
Absolutely love this jersey. I have found that with the right combination of layers (Long sleeve base, wind jacket) I will be comfortable down to the mid 30's. As cold as it gets in Northern Ca. I start a little cold but warm up to the point where I am comfortable and not over heating.
For the rest of the time (40's - 50's) I am comfortable in a summer sleeveless mesh and wind vest. As the temperature goes up I ditch and go to different layering system.
I would love another as washing and wearing for the past year (washing after every ride, and I commute on the bike) has caused the material to ball in areas, but the jersey is still in great working order.
It is a pro fit and fit like most all of castelli gear and the medium fits me great.
