I'm sick of following my dreams. I'm just going to ask them where they're goin' and hook up with them later.
Those look like they would be hot on the neck just like croakies.
I started using cablez, much thinner and dont even touch your neck when you have your glasses on. I guess they wouldnt provide much floatation but as long as the glasses are on your head there shouldnt be much chance of them falling off.
Lanyards, I use them and haven't lost a pair since.

Chums for me. Current sunglasses are on year 8. Previous pair lasted 9 years until I stepped on them (why I laid them on the floor is beyond me).
I got a little cheapo set at Walmart that's got surgical tubing and a little balsa floater. It was $4 and I don't know how bad it will torment me but it's just on my cheapos. My oakleys fit way too tight to worry about them falling.
Keep them on your nose covering your eyes and you won't have a problem
