The all-encompassing brightness of glaciers places extra demands on the eyes – demands that standard sunglasses cannot meet. Features including extra protection at the sides of the eyes and extra-dark lenses make the Nivalis an optimal choice for glacier use.
Adjustable temples ensure a secure fit around the ears, and snap-in hinges improve durability as the frames are less likely to break in a fall. A detachable lanyard can be fixed through pre-formed openings in the frame, giving extra security when worn. Grippy rubber nose pads and temples ensure the glasses stay firmly in place even during strenuous activity.
