Smith I/OS Goggle Features:
Rimless interchangeability designed specifically for smaller faces, the Smith I/OS Goggles have fluid lines and a revolutionary outrigger locking mechanism to bring the classic I/O design to an even broader audience. Featuring interchangeable lenses, the I/OS can be easily tuned to the conditions thanks to its quick release lens system. These Smith Lenses have a 5x Anti-Fog treatment and Smith use 3-layer Drywix foam to create a better seal between the goggles and your skin. Helmet compatible and with an extra-wide, silicon backed strap the Smith I/OS goggles offer both high-performance and optimum comfort.
Very clear lens changing. Very happy.
