EdifeelEdifeel Adjustable Glasses Strap, Anti-Slip Sunglasses Strap for Sports, No Tail Glasses Holder Cord, with Steel Wire Cable Eyewear Retainer (3 Pcs, Black)

Product is excellent. Tight fitting, just like I wanted. Grips glasses firmly(no chance of slipping). Would recommend to anyone looking for a nice product for a good price.

Rubber Inserts holds tight, not loose.......perfect for Active!

As advertised keeps glasses from sliding works very well. Reasonable price.

Amazing!!! The grip on glasses is nice and tight yet not bulky. The wire string on the back is strong and not heavy which makes them wearing so comfortable. The adjusting knobs are tight enough so they stay in place but not to tight so they can be undone almost with one hand. Perfect for sweaty times when my glasses slide down. I use them in surgery making me confident my glasses with stay on ...

These are very well made and easy to put on and take off and there's plenty of room to kind of move your glasses to rub your eyes if you have. And they are not real tight on the back of the head. Well worth the price

I am using the straps right now! I have glasses with no rubber nose pieces. As I sweat my glasses tend to move all over the place. It is very annoying when I am working out or working in the yard and am not able to continually readjust my glasses on my nose. The adjustability of the straps using the adjustment tabs is wonderful (tight or loose). I will say that I have grey/white hair in my old age and the straps would be perfect if they came in a closer color. The rubber that goes over my glass tips is comfortable/unnoticeable. I have had no issues wearing these all day. I would recommend the straps and would purchase them again.

Works well ,do they come longer for big heads?

This is by far the closest fit to cablz or pilotfish that I've tried. The only difference is the name brand ones are a little longer, so if you can deal w it not being as long then you'll love them! Would definitely recommend and would buy again.
