Precision-engineered for cold-weather visibility, the SCOTT 89SI Thermal ACS Goggle Lens is constructed from high-grade polycarbonate to deliver superior optical clarity and structural integrity. This specific thermal variant is designed to manage the temperature differential between the rider’s face and the external environment, ensuring that your field of view remains unobstructed during low-temperature riding sessions. The lens geometry is tailored to fit the SCOTT 89SI goggle frame, providing a seamless seal that prevents wind intrusion while maintaining the ergonomic profile required for extended trail or dual-sport use.
The integration of Scott’s proprietary ACS (Anti-Condensation System) offset vent holes represents a critical advancement in airflow management for thermal lenses. By strategically positioning these vents, the lens facilitates a continuous exchange of air that actively mitigates the buildup of moisture on the inner surface, significantly reducing the risk of fogging during high-exertion climbs or stop-and-go riding. This passive ventilation system works in tandem with the thermal properties of the polycarbonate material to maintain a stable internal microclimate, allowing you to focus on the terrain rather than wiping your visor.
Built to withstand the rigors of off-road performance, this lens provides 100% UV protection while maintaining the impact resistance inherent to its polycarbonate composition. The material selection ensures that the lens can absorb and dissipate energy from debris strikes without shattering, offering reliable eye protection against high-speed particles and environmental hazards. With no compromise on safety standards or optical distortion, the 89SI Thermal ACS lens delivers the durability and clarity necessary for confident, high-speed navigation in challenging outdoor conditions.
