Chums 5 MM Universal Fit Retainer - Patented Adjustable Sunglasses Cord (5 MM)

This is a follow up, repeat purchase. I like these for my glasses and I have glasses everywhere. I've purchased several different brands in the past but these have a good heft to them and they last a long time. They also hold the tips of the temple pieces on the glasses very securely. I'm likely to just buy Chums exclusively going forward.

It's a "Eyewear Retainer" it does what it is made to do no matter what kind of sunglasses you wear (even works fine on my $10 reading glasses!) My main problem is I'd like to find one that's alittle longer :(

I buy these guys for all of my sunglasses. The chum brand is nice and rugged and prevents me from loosing my glasses when I go fishing or for a hike. I have always purchased chums as I find them to be much better quality then some of the other cheaper brands out there. These work great and I have yet to have a pair that fails. I use these in some pretty cold conditions here in Canada. Last week it was near -15 and I had these guys strapped to my polarized glasses and they stayed put without any issues. I have had a pair of cheaper knockoff holders that actually froze and crumbled! These guys held strong. The string is very strong and secure. Your glasses are not gonna drop! The ends are made out of a rubber material that stretches and hangs on very securely to the arms of your glasses. It can take a little elbow grease to get them on but its def worth it. I found that its easiest to twist as you push them on the ends of the arms. The cinch that holds that tightens the string is made of a hard plastic and it holds the tension very nicely.

i have always folded my frames and stuck one earpiece down the front of my shirt and that generally works fine unless you bend over, then it's a big fail. i bought these because i was going on a long trip including safari in South Africa and i needed to be able to take my shades off quickly to shoot video and not have to mess with my glasses. these did the trick. i am thrilled with these for this use. i won;t use them all the time but they worked great for constant on and off demands. only downside is that junk and sweat collect on the lenses when they are off because the inside of the lenses face upwards and act like a plate against your chest.
