Lifestyle looks meet modern sport performance with Oakley's Portal sunglasses. Made with an active, utilitarian frame design, Portal also features a unique lens shape that not only looks cool, but also enhances peripheral view for more complete coverage. Constructed with O Matter™ lightweight material, Unobtanium™ nosepads and earsocks, and of course Oakley's PRIZM lenses for maximum color and clarity, these shades are as functional as they are stylish.
