I love Serengeti Sunglasses and thought I would never try another brand.  When I saw these Smith Collective Sunglasses in the black & green frame & the green mirror lenses for an unbelievable price, I pulled the trigger.  When I received them I was shocked to see these are made in Italy, which means top quality.  Very unique design, light weight and very comfortable.  Did not come with a hard case, just a micro fiber pouch.  No big deal I have plenty of cases.
