Jonny Heinkenwrote a review of Castelli RS Superleggera Jersey - Men's on March 14, 2017
Part of Castelli's Rosso Corsa (race) line, if it fits you right (you gotta be pretty slim & fit)... this is a fantastic -and really good looking- warm weather SS jersey.
Made with a lot of attention to detail. Made in the USA (unusual for Castelli). Very fine design/quality.
Superlegerra means "superlight" in Italian. So the main textile used here is a very fine, light, soft lycra. Anyway, it is strikingly soft. And very breathable. With stealthy black mesh sides.
The material may be a little delicate -time will tell. I doubt this will be your workhorse summer jersey. Perhaps reserved for more special rides?
Fit: Classic Castelli (Italian) sizing. Size up +1 from your normal street size.
***Caveat: The "no sew" arm band is narrow and does not expand much. It will definitely cause constriction (and sausage arm) on guys with larger biceps. This particular Castelli jersey is definitely best suited for fit, slim to ave. riders.
