I ordered two pairs of the Bel Air, one for myself and another for my husband. He was looking for good non-polarized glasses for the golf course, and I needed something lightweight and streamlined for running and cycling. These shades handily check all those boxes. My husband says they’re fantastic on the links, much better than the Costas he was wearing, and I love the barely-there feel while I’m working hard. They stay put, too—no sliding down the nose when you sweat, and the low-profile temples slip easily under my bike helmet and my baseball cap. The lock hinges are a nice feature that add a bit of stability to the design. We’re both quite happy with these new sunglasses.
