Adjustable Glasses Strap - Upgrade 4 Pack No Tail Eyeglass Straps, Universal Fit Rope Eyewear Retainer, Sport Unisex Sunglass Retainer Holder Strap (Black,13 inch)

My daughter used this for cheer practice and competitions. It hold her glasses in place during her 2 1/2 min routine with high intensity activity. They are comfortable and she never leaves home without them.

Fit my head well. They are adjustable. Took a bit of working the grips onto my sunglasses. But slid onto my bifocals just fine.

Work very well but each strap lasts only about 5-6 weeks. Then I have to repurchase. Good while they work.

Great for keeping my glasses on while biking and on the treadmill

Okay, so I took off 2 stars for a reason. No matter how I fit them on the arms of the frame they seem to hurt behind the ear when wearing. It’s frustrating that it doesn’t matter how you adjust it, that part just stays the same.Ironically, in contrast, the cloth band does slip sometimes so it loosens as you wear. Nothing I’ve tried will convince that strap to stay put. It’s a great concept but something about the execution is lacking.

Perfect for sports players

Bought them for myself father’s reading glasses. He said it was great quality.

Like the product but it won't work for me. I wanted to use them on my pickleball protection glasses and those stems are too big for to work well. In addition, I have a small head and I could not shorten them enough without tying a knot it the rubber
