When the ride demands full effort in cold conditions, the Men's Expedition PRO Alpha Vest delivers active warmth without the weight or bulk. Featuring 60g Polartec® Alpha® Direct insulation, it continuously releases excess body heat before it turns into sweat-so you stay dry, warm, and in rhythm mile after mile. The ultra-light Toray shell strikes the balance between breathability and wind protection (20 CFM), while stretch-woven side panels fine-tune fit and allow heat to escape during hard efforts. A two-way YKK® front zip lets you vent from the bottom and access jersey pockets mid-ride. Secure chest and back pockets stash the essentials. Finished with PFAS-free PI Dry® water repellency, powerful BioViz® visibility elements, and recycled content throughout.
