Insane clarity
Color: Matte Black/Blue Mirrored 580g
Lens Width: 64 Millimeters
These quality of these sunglasses is truly insane. They are sturdy but lightweight, and comfortable to wear for long hours driving, fishing, or doing whatever else. Where these really shine, though, is the clarity - everything is SO sharp and clear through these lenses. I got the glass lenses, so I can't speak to the "p" models with the plastic lenses, but I am very very impressed. Yes, they are pricey, but investing in these may be a good option for you if clarity is what you're after.

These are the most uncomfortable sunglasses I've ever worn.
Color: Matte Black/Blue Mirrored 580g
Lens Width: 64 Millimeters
After having these for a year, I can safely say that they are the most uncomfortable sunglasses I've ever worn. They pinch the bridge of my nose. The arms dig into my ears and the glasses slide down my nose unless I cinch the keeper strap tight. There is nothing spectacular about the glass lenses either. For this price point, I should've been wowed the minute I put them on, but I wasn't. I should've sent then back but I kept trying to like them. Now they are a $300 pair of sunglasses that live in a junk drawer.
