Treeline - Black Bronze

The Sunski Treeline is built for the brightest days in the mountains. Inspired by classic alpine glacier glasses, this award-winning frame combines modern comfort with serious sun protection for skiing, mountaineering, hiking, climbing, and long days on the water. With removable magnetic side shields and maximum coverage, the Treeline is designed for environments where reflected sunlight can be just as intense as the sun overhead.

Lightweight SuperLight™ recycled frames and Helio polarized polycarbonate lenses provide all-day comfort without compromising performance. The magnetic side shields block harsh peripheral glare while integrated perforations help reduce fogging and maintain airflow. Whether you're skinning through spring corn snow, scrambling above tree line, or paddling under the desert sun, the Treeline delivers the protection you need when conditions get bright.

From Colorado's fourteeners and the San Juan Mountains to rafting the Colorado River and exploring the high desert of the Four Corners, the Sunski Treeline is built for adventures where ordinary sunglasses just aren't enough.
