When comfort on two wheels matters, your kit needs to possess a combination of technically optimized fabrics and a perfect shape. In the case of the Castelli Mugello Long-Sleeve Jersey you get both tech-rich materials with a century of cycling expertise?complete with a peloton-complementing splash of color.Ideal for mild temperatures, Castelli constructs the Mugello Jersey out of its Warmer fabric. This synthetic textile features a fleecy inside for next-to-skin comfort, wicking performance, and thermal insulation. The Warmer fabric is also stretchy to allow ample movement, and it has a smooth face to help reduce drag.The Mugello's treated with a process Castelli refers to as Prosecco. This fabric treatment enhances the synthetic blends already inherent wicking properties by spreading perspiration quickly and evenly for efficient evaporation. This ensures your core stays dry; preventing clamminess if it's chilly or preventing overheating if the mercury climbs.Enabling the Mugello's technical properties is a body-contouring shape that packs a century of custom-tailored cycling apparel under it's belt. Castelli knows a thing or two about fit, and has defined modern cycling wear with many firsts, including Lycra shorts. An example of Castelli's innovation in the Mugello is the sleeves; they are articulated forward to provide the best fit when you're in a natural cycling position. Not only does this ensure excellent aerodynamics, it permits the Mugello to utilize the optimized fabric to its fullest potential. Out of the box, the Mugello will fit tight against the chest and unnaturally when prepping for a ride, but once seated and spinning its superior design comes to light.Adding to that design is a full-length camlock zipper that allows ventilation fine tuning that won't migrate when pedaling. The Mugello's lower hem has a wide silicon gripper to prevent the jersey from riding up, and the three rear pockets are secure and easy to reach when riding. Castelli's known for its ostentatious colors, even pioneering the sublimation dye process for enhanced sponsorship representation during early pro tours. The Castelli Mugello Long-Sleeve Jersey hits on that history with its bold graphics and eye-catching colors. But, even that's not enough alert inattentive motorists if you find yourself limping home at dusk. For that reason the Mugello has a full compliment of reflective elements for low-light safety. It's available in Anthracite, White, and Orange, sizes range from X-Small through to X-Large.
