So here's a common cold weather scenario. You're out grinding base miles in the spooky gloom of late fall, but the best route for doing so happens to include a few hills. Being dressed appropriately for flat riding in the cold doesn't mean you're equipped to handle climbs, but with the Castelli Cromo Long Sleeve Women's Jersey, you can simply unzip the half zip when the going goes up. Instead of exposing yourself to a blast of cold in the chest like other jerseys, the Cromo's separate inner lining stays in place to diffuse the cooling air and, as Castelli delicately puts it, protect your modesty. The Cromo's constructed from Strada Termico, a soft, brushed, fleecy fabric that provides fit friendly loft for insulation appropriate for the high 50s while training or as low as the high 40s during races or intervals. Strada Termico is an effective material found in various items across Castelli's line, but the key to the Cromo's flexibility as an all around fall and spring performer is the protective inner chest panel. In cold conditions, it gives a touch more warmth where you catch the most wind, and as mentioned above also vastly improves the ventilation afforded by unzipping the jersey during hard efforts or as the cold morning rolls over into a sunny afternoon. The Cromo is rounded off with the formal and functional elements that you'd expect from Castelli: a garage for the YKK camlock zipper, an extended collar, three rear pockets, and an additional, zippered rear pocket for the stuff that you absolutely cannot afford to lose mid ride. Keys, ID, candy corn. The styling is classically understated, with the jersey's solid color only broken by contrasting highlights on the chest and Castelli's iconic scorpion logos. The Castelli Cromo Long Sleeve Women's Jersey is available in five sizes ranging from X Small to X Large in the colors Azureroyal, Blackwhite, Laurelstraw yellow, Old Rosemagenta, and Violetstraw yellow.
