Lightning-fast transitions, zero lens swaps — the BOLD Flash Photochromic Sunglasses are built for riders and runners who need their eyewear to keep up. Light-adaptive lenses darken automatically in bright sun and clear up in shade or overcast conditions, so you stay focused whether you’re on exposed ridgelines or deep in the trees.
A modern semi-wrap frame delivers all-day comfort and performance-first coverage for mountain biking, trail running, gravel grinding, and backcountry ski laps. Available in Black, Blue/Yellow, and White.
