The younger brothers of the X1 Goggles, the Dragon X1s Goggles offer the same unlimited vision and optical clarity in a downsized fit suited for small-to-medium faces. The next step in Dragon's Frameless technology, the X1s features a lower-profile fit than previous Frameless goggles to create a wider field of vision without increasing the size of the lens. Spotting landings, finding hidden features in the trees, and avoiding kooks in the park just got easier with the X1s. An optically-correct injected spherical lens offers undistorted vision, and a low-profile fit, and the large lens keeps the frame out of sight for an infinite field of view. Super Anti-Fog technology keeps your lens clear, and Armored Venting circulates air and makes clearing out packed snow a breeze. Triple face foam with a microfleece lining lets the goggles sit comfortably on your face throughout the day. They're also helmet-compatible so you can stay safe out there, and silicone strap backing prevents the goggles from slipping when you stomp a big landing.
