The Flow Insulated Vest is a high-performance, packable solution designed for cold-weather cycling, offering an exceptional warmth-to-weight ratio. Engineered with lightweight Teijin Octa® active insulation strategically positioned in the front and shoulders, it provides targeted thermal protection where you need it most. The construction features ripstop fabric on leading edges for superior wind blocking, balanced by an air-permeable rear panel and laser-cut shoulder panels for optimized ventilation during intense efforts.

This versatile layer is designed to be highly packable, minimizing bulk when stowed in a jersey pocket. It features a 2-way YKK zip for easy access to rear pockets and rapid cooling, while low-profile armholes and a specialized rear elastic ensure a secure, aerodynamic fit. For safety in low-light conditions, reflective transfers are integrated into the chest, side, and rear panels.
