They fit well on my big head and are dark enough. The arm on my first pair broke and the seller sent out a replacement pair immediately, for no charge.
I am allergic to everything! I purchased these glasses because they were made out of bamboo. My two risks were 1. buying something that will not react well with my skin and 2. buying a pair of sunglasses online without trying them on first. Well, you can tell by my rating, that it worked out to my advantage:1. I’m not allergic to them. I wore them all day to an event and I was not irritated. I also loved that the hinges are set into the frame so I don’t have any exposure to the metals.2. They fit well on my face.3. I love the bamboo cylinder they came in and the cloth case it came in. But I already lost the cloth case. I’m bummed about that.4. I love how the blue lenses stand out. They look awesome in photos.5. They are light so they don’t slide off your face with your sweat. Being in the south, that’s pretty important.6. Sturdiness – We will find out. I’m pretty rough with my sunglasses. The only brand that took my abuse were my Oakley’s.So far, so good.Great product would recommend.
