Isadore Alternative Insulated Vest, a lightweight, packable insulated vest engineered to keep your core warm during high-tempo rides in cold, dry conditions. Built with Pertex® Quantum Air and Polartec® Alpha® Direct insulation, it delivers exceptional breathability and wind protection while maintaining a sleek, aerodynamic silhouette. Crafted from recycled high-density fabrics, this vest is a technical essential for winter training and transitional seasons.

Sizing tips: 

• The vest has a narrow racing cut and runs small — order one size up.
• If you have a broader chest or shoulders, consider sizing up two.
• The vest is shorter in the front with a non-stretch hem, while the back hem uses a stretchy silicone gripper to stay in place on the bike.
• A snug fit when standing upright is normal; evaluate the fit in a riding position for the most accurate feel.
