This jersey opens up an entirely new category of cool-weather clothing. All the windproof fabrics are amazing at keeping the cold out, but even with the best of them, you get wet inside with the intensity picks up. Castelli set out to make a jersey that's significantly warmer than your tradition thermal jersey but that can maintain some airflow to prevent perspiration buildup on the inside.

The fabric does the magic here. The dense knit structure keeps a lot of the wind off, which together with the luxuriously thick fleece keeps you warm to to around 10 degrees celsius/50 degrees fahrenheit. The fabric is light and extremely stretchy, so you don't feel weight down like you do with a traditional jacket.

This jersey can replace your lighte rjacket on the mild days or can keep you warm on those fall days when your vest and arm warmer kit just isn't warm enough. While this isn't a pro team piece, Castelli have given it to a few pro riders and they begged them to provide it to the team as well. Castelli are working on that.

In the same way that you can ride a lighter bike than the pros, you can also ride a better jersey than the pros. At least for a season or two!

Castelli hesitate to call this a jersey because it's unlike any jersey you've ever tried. They think it introduces an entirely new class of product. The tight knit and lofty fleece on the Polartec Power Stretch fabric helps you keep a lot of heat in, but there's enough air permeability to let a lot of moisture out. The fabric is extremely stretchy, and Castelli have given it a Hard Face finish with a DWR coating so drizzle from brief showers will run off. The finishing details are all focused on comfort and function because you'll be spending a lot of time in this more-than-a-jersey-but-not-quite-a-jacket innovative product.
