Castelli Collapse jersey

Designed to keep you warm and provide the necessary ventilation.

The thermal jersey is the first step towards clothing for low temperatures, an area in which Castelli has set the standard for clothing. And it carries on that tradition. The jersey is meant for cold days, which is why we've enhanced it with a brushed fleece lining, while retaining the stretch fabric for a great fit. Since you'll be wearing it when it's not yet cold enough to use a jacket, we've designed the fabric so that it doesn't accumulate too much heat. We think a jersey like this should be 100% functional, so we equipped it with three large back pockets, an elastic band with silicone grip, and an easy-sliding YKK® Vislon® zip.
