Every summer I lose a few pairs of expensive sunglasses. Leave them sitting on the bar, girls steal them whatever. Thankfully I discovered FOLDING SUNGLASSES like the Ray-Bans pictured below. After a day in the sun, patio hopping drinking beers I can fold them up and slip them into my pocket. Then hit the town running and still have my sunglasses in the morning! You might be a little skeptical about folding sunglasses and I was too. My advice is go try some on!
