Dragon's Terra XP collection is all about performance and versatility, and that starts with the Tracer X. The sleek shield design offers full coverage from the elements, while the Lumalens tints offer crystal clear color optimization so you can see the best way forward. Whether trail running, XC cycling, hiking or whatever the adventure, the Tracer X knows the elements and conditions can change. Quick release tabs allow for the hot swapping of the premium bonus replacement lenses so you can adjust on the fly when the lighting changes. Top it off with a ventilated brow bar, and rubber nose pads and temple tip pads, and you won't need to slow down until the sun goes down.
