Chums Switchback Silicone Eyeglass Retainer, Black/Smoke

Best retainer out there — worth every penny! I've tried multiple brands, including some pricey ones, and this retainer beats them all. My family wears prescription sunglasses, so I always keep a few of these on hand during summer to make sure the kids don't lose theirs. We've come back to buy more three summers in a row! The only small issue is that it pulls slightly when I wear it around my neck—but that's totally understandable since it's made of rubber (which also helps it stay put and not slip off!). Highly recommend—great value and peace of mind!

I bought this for my reading glasses. I tried other kind but the glasses would fall off when I hung them from my neck. This chums switchback holds my glasses securely and work great while shopping when I need to read occasionally as I go through the store.
