As the original interchangeable goggles, the Asian-fit Smith I/O Photochromic Snow Goggles are the standard by which all other goggles are measured for comfort and clarity on the slopes.
Dr. Bob Smith was a dentist, but that didn't stop him from pioneering quality ski goggles in his Sun Valley kitchen. Smith's still going strong 50 years later, and the Backcountry. com Exclusive Dr. Bob I/O Goggle pays homage to the good doctor by throwing the style back to the '90s and using Smith's first-in-the-industry quick-change lens technology. It makes it a matter of seconds to swap out crystal-clear Carbonic-X TLT lenses to suit conditions so you'll never be caught out, and the I/O also features three-layer Driwix face foam and an easily adjustable silicone-backed strap so you can always fit dialed. The lenses use Vaporator anti-fog technoology, a Porex filter, and a 5x anti-fog treatment to keep condensation from cramping your style, too, so you can ride fog-free even on the soggiest, nastiest days.
