Designed for riders who demand more from every mile, the Women's Expedition PRO Alpha Vest delivers lightweight warmth, weather protection, and next-level breathability for endurance adventures. At its core, 60g Polartec® Alpha® Direct insulation continuously regulates temperature, releasing excess body heat before it builds while keeping you warm through shifting conditions. A premium Toray ultra-light woven shell balances wind protection with 20 CFM breathability, while stretch side panels enhance mobility and help dump heat on climbs. A PFAS-free PI Dry® C0 DWR finish shrugs off light precipitation, and a YKK® two-way zipper provides adjustable ventilation and easy access to jersey pockets underneath. Secure chest and back zip pockets offer dependable storage for long rides, while an elastic hem keeps the fit streamlined for layering. Finished with BioViz® reflective details for visibility in low light and made with recycled content, this vest is purpose-built for gravel grinds, bikepacking epics, and all-day trail missions.
