Love these glases! Fit perfectly.
I have owned all the brand names of sunglasses and enjoyed them for some time. It was not until the Joplins that I found pairs that will be with me for the rest of my life.
I love the sustainability spirit of Joplins and believe they have good quality glasses. However all of them have a width higher than135 mm and I need below 130 mm to match my narrow head.
Previously I had only worn cheap sunglasses from like, Sunglass Warehouse. These definitely feel like a step up from those. They are sturdy and the polarization is notably better. The added case and cloth are a nice bonus. The lenses were a little bigger than I expected, but my partner says they don't look overly large. To me, these will be worth the price of they last me longer than cheap sunglasses. It's too soon to say that, but for now, I'm in love with these cool wooden shades!
Weight, looks and it really protects my eyes. And don't forget, it is sustainable made
