Campmor has Serengeti brand H2Optix line on sale for $40. I bought 2 Lido
versions...polarized...floating adjustable strap and come in a very usefull,
attractive looking neoprene pouch...velcro close and a clip for vest or yak
deck. It's exactly what you wanted in every category. Used em all
summer...and really like them. Dan
they weren't
a type that floats (nor were they a type specifically for boating).

o floats one way or another (whether by the glasses or croakie like strap)
o Polarized
o Won't fog up (a "feature" that my now-sunk pair suffered from) after a
while
of use.
o Won't fall off easily
o Cost $100 preferably.. My last MIA pair was $40

Any comments are appreciated..

P.S. While I did lose my sun glasses, I did bring home a boogie board and
a
(rather beat up) Kayak paddle that we found while playing around in
the
harbor...
