TIMOTHY M.wrote a review of Castelli Unavolta Jersey - Long Sleeve - Men's on May 22, 2016
Familiarity: I've used it several times
I have a number of Castelli jerseys, and all are very high quality with a great fit.
The Unavolta is a lightweight wool blend jersey, best suited to warmer spring rides.
Most Castelli jerseys run a size small, but the Unavolta appears to be more true to size, I ordered the XL expecting a snug fit, but it's more of a club fit, which allows use of a base layer underneath.
The wool blend fabric is super smooth and very comfortable on the road.
