Chums Slip Fit Rope Glasses Retainer - Unisex Adjustable Eyewear Holder Sunglasses Strap

It works well.

I love these not just to keep sunglasses around my neck but also to keep non-sport on my head when I'm doing a sport. I pull in the adjustable bead high and tight on my head and put the excess around my ponytail. It keeps my glasses in place really well, and I don't need to adjust it again until I take it off. These were also useful for preventing me from losing my glasses when tubing down a river when I got flung from my float. These fit all of my metal frame glasses well. If you need a comparison, I pair these with the ZENOTTIC Hexagon Polarized Retro Sunglasses (also an amazon purchase). They are a little thicker on the arms at the end, but I manage to get the chums over, and I haven't had any issues.

Outstanding product!!

String is a little too short for it to be comfortable when you are not wearing the sunglasses. Otherwise works and you won’t lose them when you are on the go

These are the best sunglasses retainers. They fit snugly on my Ray-Bans, and I never fear them falling off. Plus it's adjustable, allowing me to tighten it around my head and face when I'm walking or jogging.

I have other eyeglass tethers. One is silicone rubber and grips skin of neck and/or fabric on clothes like collars and hoodie and another that is like a plastic wire and it also hits collars and pushes glasses off my nose when I lean back in a chair. This rope one isn't like those and so I'm not constantly trying to move it by hand. I wear prescription sunglasses and they all help to keep them close by but during the winter wearing hoodies or shirts with collars the rope one works the best. The others look great but only use in summer when less clothing interferes.

These are great eyeglass straps because the holder is silicone so it doesn’t slip off and stays in place.

Very easy to use. Took them hiking and kayaking and never worried about losing my sunglasses.
