The whoosh of your buddy passing you through the rock garden is basically just an invitation to chase. You'll be happy to oblige in these Smith Attack MTB sunglasses. The maximum-coverage lenses use ChromaPop technology to provide amplified detail and enhanced color, so you can stay focused on the trail ahead. The no-slip temples and two-position nose pad keep them in place over every baby head and wet root. When you finally catch up and cruise back to the shuttle, quickly swap between the included bright-light and low-light lenses using Smith's Attack MAG lens interchange system.
