The PAS Mechanism Rain Jacket combines advanced weather protection with uncompromised breathability for serious cyclists. Built with Pertex® Shield Air 3-Layer fabric, this jacket delivers a waterproof barrier while maintaining exceptional air permeability—essential when you're pushing hard on the bike. The soft, quiet face fabrics eliminate noise and bulk, while a two-way waterproof zipper provides flexible ventilation options. Engineered to pack down to jersey-pocket size, it's the ideal emergency layer for unpredictable conditions. When performance demands meet weather demands, the Mechanism Rain Jacket delivers on both fronts.
