Castelli Pro Thermal Mid Short Sleeve Jersey

The key to the cool-weather performance of the Pro Thermal Mid Short Sleeve Jersey is in its use of mid-weight Warmer X-Stretch brushed fabric. It’s still got a fleece inner face for warmth, but Castelli have lightened it up a bit to make sure you don’t overheat when injecting some pace. It’s a brilliant jersey for spring and autumn and its performance can be extended across a wide range of conditions with a vest and arm warmers.

Thanks to its excellent breathability, the Pro Thermal also allows sweat to escape easily. And with more stretch, thanks to extra elastane, and a race fit, it allows for a speed-focused streamlined fit while not feeling too tight.

As a pro-performance garment, Castelli have kept details functional and focused. The YKK® Vislon® zipper slides easily, letting you boost airflow as and when needed. The drop-pocket construction allows you to load up and yet the jersey remains in a secure and stable position. There’s also a reflective stripe on the centre pocket, enhancing visibility after dark.
