Smith I/O Goggle: a one trick pony can only get you so far. The helmet-compatible I/O Goggle from Smith Optics understands this concept and counters with its Quick Release Lens System: inspired by frameless eyewear, the I/O Goggle provides quick and easy lens interchangeability; just flip the top switches, pop the lens out and replace it with a lens more suited for the conditions. It’s as simple as that. The I/O is designed to encapsulate Smith’s spherical, Carbonic-X Lens with TLT Optics that lace your eyeballs with an undistorted visual field. That’s right, these lenses don’t lie. Sealed with Smith Optics patented Vapor Lens Technology with Porex Filter that prevents lens delamination and allows the lens to adapt in changing elevations, the I/O is made with the world’s strongest thermal lens barrier. Lined with dual-layer DriWix Face Foam, you will discover the true meaning of comfort as moisture and wind are sealed out; nothing but pure visual bliss is allowed to enter through the eyes of the I/O Goggle. Enjoy its style and craftsmanship from the very first chair to the very last call of the season.
