Ditch the poncho.
Ever the forward-thinkers, the designers at Castelli decided that it was time water-repellent apparel went mainstream. After coming to this conclusion, they didn't waste any time in creating the Imprevisto Nano Jersey, a short-sleeved, full-zip, summer training jersey created to keep you dry in wet weather while still fitting and feeling like a regular training jersey. Rather than separating the Imprevisto into its own wet-weather training category, Castelli sought to construct the jersey so that it functioned just as well on dry days, becoming a reliable option in case of, not exclusive to, rainy days.
When you're setting out under gray, threatening clouds, the Imprevisto's Strada Nano fabric will loyally stand between your skin and summer rainstorms, making sure water beads up and rolls away rather than soaking through. A soaked jersey can give you a chill strong enough to cut your ride short even in June and July, and this is exactly the situation the Imprevisto hopes to help you avoid. On dry days, Strada Nano will serve to adeptly pull moisture away from your skin, bringing it to the surface to keep you cool and dry.
Though Castelli is known for its sleek, streamlined silhouettes, the Imprevisto employs a slightly boxier cut that befits its distinction as a training jersey, but it does so without veering into club-fit territory. A full-length zipper with an external flap fully seals the jersey off from water, while reflective strips on the jersey's pockets improve your visibility on days that turn dark and stormy. Three standard rear pockets allow room for ride essentials, with a zippered pocket to keep valuables safe from wet weather.
