Gatorz Delta Sunglasses
The Delta is an aluminum-frame sunglass from Gatorz with a cleaner, squarer look than its wraparound models, so it works just as well for everyday wear as it does outdoors. The lightweight frame has adjustable nose pads and temple tips for a custom fit, and the lenses block 100% of UV. It's 141mm across with 46mm lenses and a 6 base curve. Gatorz has been making aluminum eyewear since 1989 and covers its frames with a lifetime warranty. The page says the frames are "Made in USA with 7075 aircraft grade aluminum."
