Designed specifically for the AGV K1, K1S, K3SV, K5, and K5S helmet series, this accessory integrates seamlessly to significantly enhance overall wrap and comfort, allowing for extended wear without pressure. It effectively blocks cold wind from entering above the nose, preventing eye irritation and greatly improving riding comfort in autumn, winter, and spring. Additionally, it resists fogging by blocking external humid and cold air from contacting the inner side of the lens in rainy or low-temperature conditions, maintaining clear vision for safer riding. Ideal for urban commuting, high-speed cruising, group rides, and daily training, it performs reliably in hot summers or noisy traffic environments, ensuring a comfortable and focused ride year-round.
