Cold weather has a way of sorting the riders from the fair-weather. The Men's Attack Thermal Jersey is built for the ones who keep clipping in when the temperature drops. It's a long-sleeve thermal cycling jersey that holds heat without holding you back. At its core, a thin geometric grid fleece traps warmth against the skin while actively pulling sweat to the surface, so your core stays dry and steady through hard tempo efforts and long, grinding cold-weather miles. Breathable stretch construction moves with you in the drops and layers clean. Run it as your outer layer on crisp mornings, or as a mid-layer under a vest or shell when winter fully commits. Built-in UPF 50+ shields your skin on bright, low-sun days. The details earn their keep. Low-profile cuffs and hem cut the bulk for a dialed fit in motion. A semi-locking YKK® front zipper vents on the fly and stays put over rough road. Three rear pockets keep tools, food, and a stashed layer locked down with no bounce or sag. Premium 3M BioViz™ reflective hits keep you seen at 100 meters when the light goes flat. And it's made with 89% recycled polyester , so a lower footprint comes standard. Shoulder-season workhorse. Deep-winter mid-layer. Always in rotation. Ride through the cold. Don't carry it.
