Castelli introduced its Aero Race Jersey in 2007, and has been continuously improving it since. Looking to the Sanremo skinsuit, Castelli realized that a two piece kit would never be as fast, but with perfected fit and specific fabric choices, it could come close. The Free AR 4. 0 Full-zip jersey re-defines all expectations. The Aero Race jersey is both aerodynamic and race-ready. The two characteristics go hand-in-hand so Castelli constructed the majority of the jersey from its Velocity dry fabric. This material is renowned for its quick-drying properties and overall light weight -- around 131 grams for the entire jersey. Additionally, the fabric has a tightly knitted weave that increases laminar airflow over the body. In fact, Castelli makes the claim that this material is so effective that you'll save an average of 12 watts at 40km/h. In theory, this not only translates to less exertion, but around 35-40 seconds saved over an hour.Castelli expanded upon Velocity's high breathability by adding its patented Prosecco treatment. This process is a topical, hydrophilic treatment that spreads moisture out over a larger surface area for rapid evaporation. Along these lines, the rear of the jersey has been constructed from a lightweight, breathable, and yet demure mesh. While the wind naturally confronts and evaporates moisture at the front of the jersey, the rear needs extra support in both ventilation and wicking. Taking ventilation an extra step forward, the arm pits have been constructed from an even more breathable material called Nervato. With your body's natural exhaust ports ventilated, your core temperature stays regulated.The cut of the Aero Race also falls on a curve as to follow the contours of your body. Castelli used minimal seaming and paneling to reduce abrasion. However, the jersey has also been designed around the body in motion. This means that the fit is most precise while you are riding and may fit a bit awkwardly when you are not on the b...
