Another product resulting from the company’s partnership with the Cervelo TestTeam and Garmin-Cervelo, the Castelli Fawesome Vest offers a high-performance blend of wind and water protection in a lightweight, aerodynamic package. Professional cyclists can be fickle creatures. For example, Castelli’s professional riders wanted a vest that was snug, aerodynamic, and breathable; but they refused to compromise on the total wind and water protection offered in Castelli’s other winter products. Not wanting to disappoint some of the world’s best cyclists, Castelli immediately set to work. First, they obsessed over the Fawesome’s fit, ultimately creating a vest that’s nearly as aerodynamic as Castelli’s Aero Race Jersey — a form-fitting masterpiece that re-defined how we all think about race-fit jerseys.To address the request that the vest breathe while being able to withstand wind and rain, Castelli chose Gore’s Windstopper X-Lite Plus (the same revolutionary fabric used for the Gabba rain jersey) for the Fawesome. A soft 4-way stretch blend of polyester and elastane, Windstopper X-Lite Plus fabric is extremely lightweight and offers a stretchy, breathable shell that’s also wind and waterproof, making the vest a perfect option for rides in cold and wet weather. It’s no surprise that the Fawesome was a popular choice among Garmin-Cervelo riders during the 2011 Spring Classics.Other details include Velocity fabric on the back of the vest for breathability and temperature regulation and a lower back splashguard to protect you from spine-chilling wheel spray. Camlock YKK Vislon zippers are light, smooth, and stay flat when the zipper head is down, while silicone grippers on the waistband prevent the vest from riding up when you’re on the bike. Rear reflective tabs and trim along the lower hem complete the package, offering improved visibility on grey, winter rides.
