The Julbo Kids' Coach Sunglasses use high-quality Spectron X5 lenses to provide optimal sun protection for children from 3-8 years old. Julbo uses these same lenses in many of their glacier glasses, so you know they'll get the job done on a bluebird summer day. The Coach Sunglasses combine these dark lenses with a sporty frame design to give you kid serious eyewear for after-school sports and a variety of summer activities.
