Your buddy’s breath catching up to you on the rocky trail is an invitation to chase. You’ll be happy to accept it with these Smith Attack MTB sunglasses. The full-coverage lenses use ChromaPop™ technology to deliver enhanced detail and improved colors, so you can stay focused on the trail ahead. The non-slip arms and two-position nose pad keep them securely in place over every bump and wet root. When you finally catch up and cruise back to the shuttle, quickly swap the included bright and low-light lenses using Smith’s MAG™ lens exchange system.
