It´s a versatile masterpiece designed to excel across multiple disciplines, from fast-paced Road Cycling to rugged Gravel cycling and demanding MTB Cycling trails.The core challenge of cool-weather riding is staying warm without trapping sweat and overheating. The Collapse Jersey solves this with intelligent fabric mapping. It is made to keep you warm while providing enough ventilation to prevent overheating. The main body panels feature a premium Warmer fabric, which has a luxuriously soft brushed fleece inside provides warmth and comfort. This material feels incredible against the skin and works efficiently to trap a layer of air, insulating your core from the cold.A perfect fit is crucial for comfort and speed. The Castelli Collapse Jersey features a modern, close-to-body cut that minimises drag without feeling restrictive. This is achieved through the strategic use of Mid-weight Warmer X-Stretch fabric on the sleeves and side panels. As its name implies, the sleeves and sides offer extra stretch for a perfect close-to-body fit. This high-performance Synthetic material conforms to your body´s contours, ensuring complete freedom of movement whether you´re climbing, sprinting, or navigating technical terrain. The result is a sleek silhouette that performs as good as it looks.Practicality and rider-focused details are at the heart of this jersey´s design. The full zipper is an easy-sliding YKK® Vislon® model, allowing for effortless, on-the-fly ventilation adjustments to fine-tune your comfort. A protective flap at the top of the Round collar prevents the zipper from irritating your neck. At the waist, a gripper elastic holds the jersey firmly in place, preventing it from riding up and exposing your back to the elements. For carrying essentials, three generously sized rear pockets are positioned for easy access, providing ample space for nutrition, tools, and a vest.
