The ASSOS Spring Fall SS Skin Layer P1 is a re-engineered first layer designed for peak performance in cool conditions (12–20°C). Now 15% lighter than the previous generation, it features a specialized body-mapped weave that is tighter on the front for core insulation and more open on the back and underarms for active thermoregulation. The single-piece, seamless construction provides a friction-free, second-skin fit that maximizes moisture management. This updated version includes increased collar coverage for better protection and a refined, carbon-infused textile for permanent odorControl. By effectively pushing moisture away from the skin while pulling warmth toward the core, it creates a stable microclimate during high-intensity efforts. Designed to integrate perfectly with the Spring Fall jersey collection, it is the definitive foundation for the transitional riding seasons.
