Sometimes simple is best. With a bold, adjustable strap + frameless lens for unrivaled peripheral vision, Loki will give you the best vision on the mountain. The classic Revo Light Management System (LMS) protects eyes from UV rays, blue light, and High Energy Visible (HEV) light, and the Revo Polarized Photochromic Light Management System (PPLM), exclusive to Revo goggles, automatically adjusts to accommodate changing light conditions while allowing you to still read a digital sign or watch. A double lens and ventilation help prevent fogging, and triple-foam protection keeps these goggles snug on your face. What else is there to think about?
