Michael V.wrote a review of Castelli Perfetto Light Short-Sleeve Jersey - Men's on June 4, 2019
Familiarity: I've put it through the wringer
Fit: Runs small
On the pacific coast it's often wet, cool and foggy on morning rides. This jersey is my favorite pick for temps in the mid 40's (with an added layer) to low 60's. Extremely versatile with great wind protection. I've yet to overheat. It's simply a great combination of tech and fit.
I'm 5' 7" 135 lbs, 35" chest, and have both small and medium in this jersey. Small is body-hugging, better without a layer. Medium, I can layer up for cool mornings, and remarkably not overheat. Love it. Fine in light rain. Surf blue stands out in the fog.
