You don't need to be a fighter pilot to enjoy the aviator-inspired style and lightweight protection of the Altro Adala Polarized Sunglasses. However, the lightweight, durable stainless steel frames have nickel silver temples and a nose pad to keep these shades comfortably on your face if you are at 50,000 feet. Plus, the polarized, polycarbonate lens enhances colors and clarity while reducing glare for a sharper view. They're also impact-resistant and shatterproof to keep them intact when you take an errant volleyball to the face thanks to the spontaneous match that your fellow pilots decided they just had to have.
