The Castelli Pro Thermal Mid LS Jersey is a quintessential piece for cyclists who seek both warmth and performance in cooler conditions. Crafted from mid-weight Warmer X-Stretch brushed fabric, this jersey is adept at providing essential warmth while maintaining breathability. Its brushed interior feels soft against the skin and traps body heat, making it ideal for rides in cooler weather, either alone or with a vest for added protection.

What sets this jersey apart is its race-cut design. The highly elastic fabric offers a close-to-body fit that contours to the rider's shape, ensuring aerodynamic efficiency without feeling overly tight or restrictive. This feature is particularly beneficial for competitive cyclists who require a balance of comfort and speed.

The jersey also boasts a drop-pocket construction, a thoughtful design element that ensures a better fit around the waist and optimizes pocket position for easy access. This feature enhances practicality, especially during long rides where access to nutrition and essentials is crucial.

Additional attributes include an easy-sliding YKK® Vislon® zipper, offering effortless adjustments on the go. The embossed line across the chest adds a touch of style, while the reflective vertical stripe on the center pocket enhances visibility in low-light conditions, ensuring safety during early morning or late evening rides.
