Lenses are replaceable and they "open" outwards.
A little padding around the frame which is very comfy.
Anti-fog is excellent, even in cold water/hot humid conditions.
Tough to get washed off your head in a slam

but they DO float!
Lenses are tough - very hard to scratch.
Almost total coverage by the lenses - no water in the eyes!
Yes you get water on the lenses and they spot (gunk in the water sticks I reckon) and yes you do get used to it - but you get more used to NOT being sprayed in the eyes so taking the glasses off is a bit of a shock at first

The Sharks are good for a 3 or 4 hour session without needed to be cleaned ...
I got a free pair to demo since last year and use them a LOT - so much better than the SeaSpecs (dont float!) or the Wiley-X (fogs easily) glasses I used ... so good in fact, I bought my own pair of the old version (different strap system) and will eventually buy V2 when I ruin my free ones!
Been treating the demo ones pretty badly - not bothering about sunblock, wiping off the lenses with salt-encrusted t-shirt, not washing in fresh water, just yanking them off my head when the sun goes down without loosening the strap ... they still going strong!
I had 3 pairs of SeaSpecs and they all sunk the millisecond they came off my head

so the Sharks are much cheaper in the long run!
I agree I tried about 10 pair of glasses two years ago. I use these for kiting and flying and motorcycle. The quality/fit is great. I did a buch of reviews here (do a search) all the above is true. Last sea spec's I got the lenses where all deformed and I chucked them.
