The FRENSON FOCUS FogFree orienteering glasses are true anti-fog sports glasses with ventilation holes to prevent glasses from fogging up, especially when it's raining or humid.
The FRENSON FOCUS FogFree features a lens with ventilation hole, with the top portion of the lens used for distance vision and a magnification area at the bottom for close-range. You can read your map or bike GPS/computer while running, hiking or cycling.
These FRENSON FOCUS FogFree orienteering glasses are lightweight, made from impact-resistant polycarbonate material, with shatterproof lenses. They also feature an adjustable, non-slip neoprene lace for a perfect, custom fit.
