I have 4 pairs of Whiskers, 3 of which are the ti frame. They are extremely light to wear and the replacement nose pads and ear pieces are only $9. They are an all purpose frame in other words you can wear them with a suit and tie or shorts and a shirt. I always keep a pair in my vehicle as they fit nicely in the factory overhead sunglass storage pocket. If you can get a ti frame, do it and down the road pick up some extra lenses
