Polarized Helio Lenses

Polarized polycarbonate lenses deliver premium optics and durability for high-performance adventures.

Made from SuperLight, our proprietary recycled resin rescued from a US landfill. Lightweight, flexible, and planet-friendly.

Lightweight, flexible frames with sculpted contact points for stable, pressure-free wear.

All Sunski frames are covered by our lifetime warranty. Best story on how they broke gets extra brownie.

Design & Fit

Treeline is our Reddot award-winning, medium–large Alpine frame built for maximum coverage and serious sun protection. This unisex style blends bold performance with everyday wearability — a go-to for spring skiing, mountain pursuits and long days on the water.

Removable, magnetic sunshields, a trademark of all Sunski Alpine shades, block harsh side glare. Perforations reduce fogging and maintain clear peripheral vision. Extra-dark lenses paired with the sunshields make it ideal for prolonged exposure in bright alpine and on-water environments.
