You can only scope your line if you can see where you're going. Putting on the Smith I/O MAG goggles is like flipping the switch from regular to widescreen. Lenses are anti-fog, wide-angle, and crystal clear. Comes with the bright lenses, a variable mid-light lens, and a low light lens. Altogether you’re set for any condition, and if you’ve got a Smith helmet, these integrate seamlessly.
