For riders who refuse to ride inside on a trainer during the winter, a warm thermal jersey like the GOREWEAR Spinshift Thermo Long-Sleeve Jersey is a must-have. The body construction combines a water and wind-resistant thermo-woven fabric with a highly elastic fleece on the back and arms to keep the core warm and dry without sacrificing breathability. Three open rear pockets and a smaller zippered safety pocket keep our essentials along for the ride, while a silicone gripper at the bottom hem helps keep our jersey in place.
