Seek out aerobic adventure in Tifosi's Seek FC Fototec sunglasses. These lightweight, full-coverage shades boast Tifosi's exceptionally tough Grilamid frames, while their Fototec lenses automatically adjust to the light conditions so you always have the perfect tint. Their open-frame design and large, impact-resistant, polycarbonate lenses offer a wide field of vision while protecting you from debris. Plus, you'll love the hydrophilic rubber nose pads and temples that adjust in all directions and grip better when wet, for a custom fit that stays put.
Tifosi's Fototec lenses use variable tint technology to rapidly adjust to changing light conditions for superior clarity and protection. In bright sun, photochromic particles embedded in the lens react to UV rays, darkening the optics so you'll never squint. With cloud cover, the particles return to their previous state to let in more light.
