The Oakley Splice Snow Goggles are a reinvention of the gravity sport goggle from scratch. Try a pair on to experience the unbelievable comfort of the skeletal support system. It took a ton of anatomical engineering, and the end result is a unique architecture that spans the entire nasal area. The internal support system reduces pressure on the nose by tuning the distribution of contact forces across critical zones. As if that's not enough, it also maximizes airflow. The support system works with O Matter® frame material that remains flexible even in extreme cold. Combined with moisture wicking triple-layer fleece foam and strap outriggers that evenly balance pressure, the system makes this design one of the most comfortable goggles ever created for winter sports. Splice has an interchangeable lens design that features semi-flush lens mounting, a means of optimizing downward visibility. Side-to-side vision is also maximized. Even the strap outriggers are engineered to stay out of the way and help maintain a panoramic view with wide-open peripheral vision. All Splice lenses are dual vented and feature Oakley's F3 anti-fog technology. The Dark Grey (17% VLT) Lens is a Protection Level 3 Lens for contrast in sunny conditions. UV protection of Plutonite® lens filters out 100% of UVA/ UVB/ UVC & harmful blue light up to 400nm.
