Serengeti bormio sunglasses - lightweight, too lightweight - Serengeti Bormio Sunglasses

I had a pair of Serengeti sunglasses that I purchased for skiing. I loved the glasses and wore them for everything. They were my "go to" sunglasses. Well, they finally broke after many years. I purchased this pair and I am a wee bit disappointed. They are lightweight to the point of appearing to be almost disposable. I bet they will be "one season" sunglasses. I never would have purchased these sunglasses in a store. Too lightweight. I would have returned them, but I needed sunglasses at the time. Luckily for me, I found my old pair of Vaurnets.
