Typical great quality Castelli product. Perfect weight for Pacific NW autumnwinter rides. I usually wear a Medium jersey but went up a size as recommended on the WBW website, and they're right. The Large fits me perfectly, although I'm just 5'8 and 142 lbs.
This jersey is great for layering in cold weather, I've worn this with a thin base layer and a Gore windbreaker and started getting too warm when it was about 35 degrees. I've also worn just the jersey when the temperature dropped from 42 to about 36 after dark and stayed warm enough, it was a 40 mile ride so I was getting pretty cold at the end but not hypothermic by any means. A good thermal windproof baselayer combined with this jersey would likely be ideal for temperatures hovering around 40 degrees.
As expected from Castelli the quality is excellent, the jersey fits well and is comfortable.
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.
