Essential winter warmth. The perfect balance of insulation and breathability, the Chillblock was designed to adapt with the seasons to keep you comfortable no matter the weather. Luxuriously soft microfiber fleece allows this jacket to be worn by itself or layered over a jersey, it’s high breathability keeping you from overheating on tough climbs while trapping precious heat on the descent.

Subtle reflective accents on the rear increase safety in low light while reinforced rear pockets maintain shape when packed full. Cut in our signature Race Fit: slim through the torso and arm. Due to the high stretch of the fabric, if you’re between two sizes we recommend the smaller option.
