Our review
A timeless look with subtle curves, the Duncan frame is iconic. Crafted with our proprietary OX2 lenses (blocking 100% UV light), you’re fully prepared for a no-glare, crystal-clear experience. Made from TR-90: the Duncan frame is lightweight and highly durable. Our Gator Grip technology prevents slipping and sliding when you break a sweat - So get ready to explore any trail, summit, or water way!
