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.
