String like a round shoelace
Size: 28 in Color: Black
I like these due to being soft and easy to pull my sunglasses down and have them right there and put the on and wear and not feeling them on my glasses. Can tighten strap if needed or leave loose if just wearing and want ease of raising and lowering.

Does What It's Supposed to
Not much to get excited about here--it's a nerdstrap for your very expensive Costa sunglasses.

The Fathom Cord eliminates this potential tragedy. ... show more

Best I’ve found
Size: 28 in Color: Costa Blue
I’ve had a lot of glasses straps. Always wear them kayaking or at the beach. This is by far the best in terms of reliability, toughness (only word I could think of at the moment),and ease of adjustment.
