... +1 for sunnies.
Helps stop spray or indeed if it rains and of course when its sunny.
I used to have Seaspecs but now have some generic Spotters with cable ties acting as the strap. Yes, cable ties,,,, thanks Jamee for the brilliant idea. Started out as a temporary measure but to my surprise works great, year later and still haven't come off. Mind you, if they do then they are definitely not floating so expect them to be gone!
Either way, I reckon get sunnies!
cheers,
Robbie
ps make sure they are polarised.
