The Nike Khyber goggles have a large-fitting frame that yields an even larger field of vision, and the Transitions photochromatic lens adapts to light conditions on the go, eliminating the need for multiple lenses. Integrated outrigger construction gives a secure fit with universal helmet compatibility, and a unibody ventilation system provides maximum breathability. In addition, triple-layer face foam combines with a heat-retaining microfiber fleece lining to keep your face warm and toasty in nature’s harshest conditions.
