Adjustable Sunglasses Strap/Lanyard Sports Glasses Retainer for Men Women and Kids Color Combos Pack of 2

Keeps glass in place

These are cute but they will not float and will not prevent your glasses from sinking. Probably would be OK in a swimming pool but in a lake you'll lose your sunglasses. That said for price they work great as retention straps.

Its help for what my mom needed but the adjuster fell off so now its just hangs there.

They look like they will hold up well.

Fit glasses perfectly and look great

My sunglasses/glacier glasses have side guards which I like. But to make them work properly, I need to be able to snug them up against my face. But when I take them off, I want to loosen the keeper cord so that they hang on my chest, ready to put on and snug up again. I was out for a winter walk, had these on my chest with the cordlock about halfway to the end. Wanted to put my hood up, and realized I needed more slack in my keeper, so grabbed the cordlock and pulled back. Based my experience with other keppers that have a cordlock with two holes, I pulled back firmly on the cordlock. It came off in my hand. Hmph. My bad. But rather than going back to one of those with a two-hole cordlock - one that's a lot harder to adjust - I put a small split ring on the end of the keeper, as shown in the photo. Now I have an easily-adjustable keeper but one where the cordlock won't come off if I loosen it all the way.

The media could not be loaded.  Real stretchy material and the fabric was soft. Difficult to put on without any special tools.

Had them before. Saved so many glasses from getting lost
