“I’ve worn the burnet frames for years now. The fit and performance of the whole product is unmatched compared to any other sunglasses on the market - period. I’m a landscaper and rely on a solid pair of sunglasses each day, all day, every day. The color separation and clarity of the SR91 lenses is flat out amazing. They never fall off my face despite sweat, water, anything. They are comparable to wear all day without feeling tight or encroaching. At mid day or morning sun, the color separability is pure bliss. At dusk, they brighten up my vision! I also do a lot of hiking, running, and skiing, and the burnet frames are on my face at all times. I will never need to look elsewhere - I’m convinced these are the best frames and lenses my money can buy. You won’t be disappointed.”
