Extremely Comfortable, (only complaint about these glasses is when you eat while wearing the sunglasses they slide down your face "just a little" needing to be constantly pushed back in to place. that being said it's only while eating you can jump backflip run and they stay in place) hard shell case included. The tint enhances natural color, blues and greens stay vibrant and give everything a "movie film look". It docent just darken you can use in low light, the darkening makes things look Hi-deff. there're sort of a sporty aviator style, unique. oh yeah All native products are Quality polarized not extra deniro like Oakley's and they come with swappable lenses. Life time anything warranty.
