Chums Original Cotton Safety Eyewear Retaine-Unisex Keeper for Sunglasses-Adjustable Fit & Made in USA (Standard-End Size)

Works well on Maui Jim's prescription sun glasses, cotton is comfortable in hot and cold weather. The elastic ends hold well over time. I usually get new ones because of some color fading over a year of everyday use. I work outdoors a lot.

I love everything about this strap. The material is so soft and comfortable. The length is perfect and adjusts easily but yet stays put. Grip on the glasses is great. The color is vibrant and beautiful! I love them!

Great product

Its a little wider than expected, but works as expected. It's a good purchase.

I liked the length of the product. It was long enough to freely and easily get over my head. I wore them on my sunglasses while jet skiing and felt very confident they were holding my sunglasses on very securely. It was very comfortable around my neck. I got a bright blue color to make it easier to find. It truly helped when trying to locate my sunglasses amongst all my beach items. It was very easy to put them on my sunglasses. I felt they were snuggly fit.

I bought this to replace a similar loupe retainer I wore out. They may be too heavy for sunglasses but they have lighter ones that may be more appropriate. They work great

Keeps my glasses in place well.

Comfortable. Fits on the frame perfectly.
