Folding sunglasses are a hard thing to understand until you actually own a pair. On one hand, the idea of being able to fit a pair of sunglasses in a case the size of your wallet and take them with you everywhere is very convenient. On the other, how do they not get destroyed mingling with the other stuff in your pocket–especially when you consider the fact that there are additional moving parts? We can’t quite understand how we haven’t destroyed every pair we own, but that just makes us more excited about these Spy Fold sunglasses. They’re custom-built of “virtually indestructible Grilamid” (Google it, it’s a real thing) and sturdy five barrel and pin hinges. The lenses block 100% of UVA, B and C Rays (Spy’s so called “Happy Lens” technology). They come in black, black or more black. As if all that isn’t enough, the pouch can double as a wallet.
