Sage Cattabriga Alosa's signature IO 7 Bonus Lens Goggles bring Sage's same unique style, vision, and performance to the table. With a frame less construction and spherical lens, you get full peripheral vision, so you won't miss that little kicker in the trees. TLT tapered lens technology optics don't distort your vision, so you can be sure that you aren't miscalculating the steepness of your line. Smith has pulled out all the stops to make fogging a thing of the past with its 5x anti fog inner lens, vaporator lens, and Porex filter, plus you get the Green Sol X lens and the Extra Red Sensor lens. And with it's 3 layer Driwix face foam, you might just forget you're wearing goggles at all. So even though you might not be steeping up to the same big lines as Sage, at least you can enjoy the same crisp vision and anti fogging technology.
