Review on Cablz CZZIPZB16 ZipzB16: The Ultimate Zipper Eyewear Retainer by Toki Louton

I have a medium sized head and ordered a 16 inch length. But even when I pulled them all the way down, they were probably still sticking out 2 inches at the back of my head. As mentioned elsewhere, this became an issue because of car headrests pushing the glasses off my nose, and it also happened when my neck rested on something again. When I tried to undo them to take them off the other day, I ripped a small bead and washer out of the rubber attached to the temple. And that's the end of them in about 8 months. I'll try the Croakies mentioned in other reviews here, which have articulated arms to allow the cable to slide freely down the neck.
