The Mechanism Shell Jacket is built to keep snow and rain out, designed for harsh conditions. Constructed from a 3-layer Polartec® Power Shield™ Pro fabric, it offers full waterproof protection without compromising on breathability or flexibility. The Polartec® Power Shield™ Pro is a high-performance, waterproof and breathable non-PFAS membrane made with plant-based Biolon™ nylon. Strategically placed stretch panels with a mesh face enhance movement and ventilation in high-sweat zones. The jacket’s slightly looser fit allows for effective layering, while a soft fleece lining adds extra comfort. A two-way YKK Vislon® front zipper provides adaptable ventilation and easy access to jersey pockets. Two rear zippered pockets provide storage, and a single-sided drawcord at the hem allows for an adjustable fit.
