【HIGH-STRENGTH LIGHTWEIGHT MATERIALS】We've decided to produce our collection from the high-grade Japanese TR90 used in aerospace technology as it has the highest strength-to-weight ratio of any metal. This also means our glasses only weigh 17.05 grams. You can wear them for hours and forget you have them on.
