Created for performance on and off the bike, the Define sunglasses epitomize function and POC's active heritage. With a lightweight grilamid frame for flexibility and durability, and hydrophilic rubber grips on the temples and nose piece, the glasses stay firmly in place even under intense periods of activity. Featuring Clarity lens technology, the lenses control the color spectrum for enhanced contrast and color definition when riding MTB or in urban settings. The lens is shaped so it is possible for corrective optical lenses to be fitted. Designed for use on the trails but equally functional in everyday settings, the Define sunglasses offer a seamless fit with the Axion helmet.
