Back in the summer of 1999, Castelli introduced simple jerseys.They were elegant but not plain. Today, the Prologo HD jerseys offer the best of that idea. Simple but not plain was the Castelli vision for a jersey, and the Prologo has it with style. The Prologo does this with subtleties, showcasing ingenious technological traits. Such as reversed arch pockets, that prevents pocket sag and our proprietary Stratus two-layer fabrics which makes a base layer nearly obsolete.

Don't know why they stopped making these
This is a great wind-resistant base layer that Giordana no longer offers. I was happy to get what I assume was NOS for a great price. Classic Cycling was great from a customer service perspective. I'll be buying from there again.
