Gorewear Spinshift Thermo Long Sleeve Jersey The warmest Gorewear cycling jersey, the Spinshift Thermo Long Sleeve Jersey is ideally suited to the demands of riding through the transitional months of the year. Whether it's a chilly and damp autumn day or a cool blustery spring ride, the wind-resistant and water-repellent thermo-woven fabric gives reliable weather protection to your core. Across the back and to the arms, a high-stretch breathable material provides excellent heat regulation, ensuring comfort on rides that vary in intensity.  Gorewear has given the Spinshift Thermo a slim fit, removing energy-sapping flapping, and conserving watts for the final push to home.  However, plenty of stretch in the jersey ensures you can move easily about your bike. A total of 4 pockets, one of which is zipped, gives plenty of space to stash ride essentials.
