"What Our Gearhead® Experts Are Saying:""I’ve skied in the Vantage 2 Mips Helmet on everything from storm days to spring laps, and the upgrade is huge. The new Fidlock buckle makes it super easy to clip in with gloves on, the BOA fit system locks it down comfortably, and the extra venting really makes a difference when you’re bootpacking or skiing hot laps.""The I/O MAG S takes the same optical platform as Smith's full-size I/O MAG and scales the frame geometry down for smaller faces, including a Low Bridge Fit option for a wider or higher cheekbone shape. The Responsive Fit frame flexes to follow the face rather than sitting on fixed points, and the five-layer anti-fog treatment on the inner lens works in tandem with Smith helmet venting to stay clear through temperature swings."
