The quality, durability, and convenience of being able to carry these sunglasses anywhere in your pocket is phenomenal! This will be my go to brand as long as the sun shines! I also get a lot of compliments on them when they are on and people are shocked when they see me fold them up because they don't look like folding sunglasses when on. I was also shocked at how light they were, you barely notice they are on while also feeling like they will stay securely on your head even with a strong gust of wind. Again, the quality is phenomenal! The only reason I reduced one star is due to two factors. The lens colors are confusing (Copper had a blue tint, moonrise has a grey tint, sunrise and grapefruit have a green tint) which they don't explain well in the website. Customer service gets an A for explaining it to me clearly so I could replace with a more preferred tint! And two that I am not a fan of blue, green, or grey tints. The beauty of polarized sunglasses is that they usually make what you are looking at look bright while also protecting from the sun. The green tint I originally purchased was dull and dark. I recommend the Sky tint as the best option I have found so far but would like brighter (yellow tint maybe?).
