I think most sunglasses are overpriced but I was willing to buy these on sale to replace my old pair broken in a crash. The old pair lasted well over 15 years and I expect no less from these. Excellent protection from both sun and wind.
I'm so happy this M frame fits the M frame lenses of old! I have three lenses from a pair I had a while back that suffered a broken frame. I've always liked the M frame because it fits close to my face. This pair from BTD was just the right price!
