Worn daily for two years. - Julbo Micropores PT Mountain Prescription Black Sunglasses with RX Single Vision Lenses

Solid well built but has two replaceable parts that will need periodic replacement with constant use. Those being the nose pad which is excellent in comfort, but wears out quickly; the foam covering the piece that rests on your ear also wears out quickly. As for wear-ability and eye protection from debris in the wind they are great. Blizzards on the rez in SD are no problem.
