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

Stable, easy to use. Great fit for my loupes. This is my second set I’ve used on these loupes of mine. Super comfortable and comfy! They work great.

First time buying this brand. At first I was a little disappointed because when they first they arrived they would not slide on the ear pieces of my black frame "Blues Brothers" Ray-Ban Wayfarer frames of my eyeglasses. So I looked them over and couldn't find any defects in workmanship the stitching that I could see was actually very nicely done with the correct thread and correct upper/lower machine tension. So I gently slid the ends that go over the ear pieces over a hard plastic toothbrush handle almost the same size as the Wayfarer frame just a little smaller. When I slid each side over the plastic handle I noticed that what was stopping them from going on was glue inside of the openings which is not a big deal in fact it shows me the manufacturer is not afraid to use enough glue for the job. So now I clean my wayfarers with lemon pledge like I always have and wipe them clean. The retainer went onto the ear pieces perfectly not too tight not too loose just right the second try. So far they feel pretty good they keep my eyeglasses from falling off my face leaning down, they work great on a motorcycle, and I think they are going to do the job just fine for me. I would like to see if they have a design similar to another brand I have used in the past because I like the craftsmanship and quality of the retainer. Thank you very much.

Chums on all my fishing glasses. They work really well for me.

I like these and they work pretty well. They don't fall off and you can tighten them to keep glasses from sliding down your nose. The only thing is that they're probably best suited to people with short hair. I have long hair and when I try to adjust them, the slider ball thingie gets caught in my hair and almost every time a few hairs get pulled out. Ouch!

After about 20 years my previous Chums retainer wore out from many, many water adventures. Bought this one to replace it. It's still the same quality product. Fits well, durable, good looking. Excellent product for the price.

I bought these for my dental loupes, which are quite heavy and need a substantial strap to hold them in place while I am leaning forward. The standard size fits very well, very secure. The only thing I would change is to make it easier to adjust/slide the cord lock with a spring cord lock (like you would find on a jacket etc.); since I have to take these on and off many times during the day, and the bead fits the cord so tightly, it's awkward to adjust (I may change this out myself if it doesn't start to loosen up with wear). But overall it's very well made.

I had lost my glasses several times while climbing walls at the gym. So I needed something to secure them. Love this product! Keeps my glasses on and is comfortable.

Super cute. Extra long. Really difficult to adjust. Tried sliding the adjusting ball several times thinking that would help loosen it a little but it didn’t change. Caught my hair in it several times in the process.

Put this on a pair of Oakley Radars. I prefer having them cover almost the full temple as pictured. Initially I couldn't get them past the temple tips but then realized that the Radar temples had a removable synthetic sheath. Removed them & complete full installation ensued as I had envisioned. Happy with the result.

Es muy Buen Producto y cumple con su función, pero es algo pesado y si alguien mueve el retenedor ó tu por accidente, te atoras ó lo jalas si puedes sacarte las gafas.

very useful, prevents you from forgetting where you put your glasses and stops the glasses from slipping down your nose.

Amazing

Exactly what I thought it would be. They’ll fit most glasses other than thin framed glasses
