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.
