Handcrafted in Italy and an industry first, Aerowing Lamon goggles feature an eco-friendly, vegetable-oil-based frame material that is durable, lightweight, strong and resistant to the harshest conditions, while reducing our carbon footprint. The wing-shaped eyepiece design, with its split edges, diffuses air so that it exits smoothly along the length of the lens. Diffusing the airflow along the edges of the lens also draws in more fresh air behind the lens, preventing fogging. Two ventilation ducts provide additional airflow.
