This is a great jersey for cool weather (60F - 5) . It has good wind stopping capability so you don't chill on downhills. Castelli styling is second to none. Rear pockets and zippers all perform flawlessly. Like all Castelli gear you need to buy a size or two up from what you normally buy.
This is my second jersey of the same model, as always the quality is top notch and the fit is perfect for my smaller size, very comfortable for the coldish California winter, I have been waring Castelli garments for at least 30 years now and they have never disappointed me
I've been using this jersey worn over a couple of mid-weight layers down to about 35 degrees and with an added windbreaker down to about 20 degrees. Using it for both road riding and with the Fatty on snow covered trails.
Well made & keeps me warm. Ordered an XL (my usual size is a Large, but I've learned the hard way that Castelli can run really small.) The XL is plenty roomy as it turns out & I probably could have gone with a Large if I was not going to wear more than one layer under it.
