I've been quite unsuccessful at getting my sunglasses to keep a tight fit on my face. Granted, I don't have the $100+ Oakleys, but I did previously try $70-$100 Bolle and others, and those start sliding down my face after I start sweating it up as well. I think my profuse sweat and my nose structure simply makes it hard for glasses to get a good grip.
I was looking for some device to keep my glasses up. Croakies carries a whole line of stuff that seems interesting, and I'm sure most of them work, but I want something that works well.
I tried a "Terracord" (a simple cord which slides onto your earpieces, and then you pull the plastic knob to tighten on your head so that the excess cord dangles off the back), but I find the dangly extra piece annoying.
Croakies does have some earpieces ("Reax") that look promising, but I've never used them.
Anybody have any opinions/advice?
