Based on feedback from BMC team riders, Assos constructed an even lighter skinFoil option for the year’s hottest days and most strenuous situations: HotSummer NS SkinFoil Evo7. The textile is spun on tubular machines, much like socks, which gives these skinFoils a seamless construction for better fit, improved performance, and more comfort. The HotSummer NS SkinFoil reacts to the intensity of your sweating and the subsequent cooling effect with what Assos refers to as a push-pull effect that works as your personal micro-climate, essentially pushing moisture to the next or outer layer to cool you down when hot, or pulling it back as insulation when cold. High performance jerseys and jackets may not reach their performance potential if your first layer does not function properly. Ensure you and your gear are at peak performance with this baselayer from Assos.
