These are great. I purchased them and another set of Serengetis at the same time and fell in love with these instantly because of the comfort. They are almost weightless and fit my face very well. The optics are very good too.
The only downside and I was aware of this before I purchased them, is that the non-hinged design means it isn't a good idea to try and temporarily hang them from your shirt collar when you go inside or something. Bend over even slightly and they fall.
Pros: Light weight, comfortable, great optics, fit me well
Cons: Hard to hook in shirt collar for temporary storage.
