12. Airframe is the lightest and hingeless sunglasses.

If you need to buy sunglasses in Japan, try Airframe of JINS, as it is a high-quality product.

This is “JINS & SUN SPORTS Hingeless”. It is also good for running and exercise.

Airframe is a brand of spectacle maker, JINS, whose stores are located throughout the country.

As you can see all kinds of products on the website below, Airframe has a lot of types of glasses. But the common denominator is they are all super light and comfortable to wear. Temples of glasses are thin, flexible, and tough because they use PPSE resin. The temples made by this resin can provide a special feeling, like “it is holding your head gently”. Also, there are no hinges, so AIrframe glasses are super light and durable.

Although there is a range of prices, some of them such as the sunglasses above(the product page) are super low in price, ¥3300. Actually, I got this for half price at the sale on their website!

But there is a downside. Because of the lightness, it’s easily lost. Actually, I lost twice. Be careful. Also, the temples and lenses can be easily detached, such as when put inside your pocket. But you don’t have to be disappointed. It’s also easily fixed like the snap button of a shirt.
