The women's version of the I/O model features magnetic lens, allowing the easiest lens replacement in history. Magnets are supported by two locking mechanisms that keep the lens in place even in case of a difficult fall. However, they do not have any impact on the ease of replacement. Thanks to their shape, the goggles are compatible with all Smith helmets and support the AirEvac system for moisture ventilation. The unique Responsive Fit copies the shape of your face. Their spherical lens is one of the largest ones in the collection and thanks to the Carbonic-X treatment is also scratch resistant. Great functionality of the goggles is complemented by the 5X anti-fog treatment and the Porex filter that balances the temperature and pressure between the glasses. The I/O MAG S is the highest Smith model with the top technologies that provide comfort, so you can fully focus on your fun.
