When I received it, just looking at it I thought I might return it. Reason - on my first few tries , the grips on my nose started hurting and that concerned me. Primary reason for me buying this was the fact that I needed it for a cycling event. Decided to give it one more try and boy I was glad I did not return. Did a 62 mile bicycle ride in rainy and windy conditions. These hold good on the eyes, no moisture accumulation and not once they fell off or were loose. What I like the most was the extra rubber on the top of the frame which prevented wind and water from seeping through the top of the sunglasses. Worth the buy
