ChumsChums Neo Megafloat Sunglass Retainer - Floating Neoprene Eyewear Strap for Large Frames (Black)

Was worried it might not fit the thicker than normal ends of my glasses but it fit no problem

私のサングラス（オークリー）は、海で使うのでフローティングのものを探していました。早速、セットしようとしましたが、ツルの差込口が小さく全く入りません。遊びもなく、どうすることもできません。それからフロート部分が少し重いように感じました。

This retainer design does not hold the arms of your glasses tight enough to prevent being pulled off. Float is large and literally pulls strap off, so no use for water sports, or any other active outdoor activity. Refunded, once again excellent service from Amazon!!

I thought I was ordering the YELLOW retainer, however it defaulted to black. Also, when you pick the color, even the black option shows the yellow retainer ... which makes you believe you are getting the yellow one. Anyway, I would have sent it back but was leaving the country the next day and didn't have time. I'm a little disappointed as this black retainer is going to be very difficult to spot in our murky lake. :-( If the seller reads their reviews: I suggest you correct the color options so that the black option shows a black retainer and the yellow option shows the yellow retainer.

Not very comfortable, they could be tighter on the glasses. I have smith lowdown steel xl’s so the frame is pretty large but still not very tight.
