Irtrogdor -
I'm also checking out the Oceanos Grey in 5mm...Seems like a good deal for the money...I won't be getting mine until spring...If you get yours before me let me know if you like it or not!
From what I hear 3-4 years of GOOD service is all that should be expected out of ANY quality "open cell" wetsuit. The only bad things I've heard about the Dive Skin brand or Oceanos suits is that the fit isn't AS perfect as an Elios...And that SOME people had issues with the glued seams I think...That info however is a few years old...I wrote Dive Skin to ask if this is still an issue...No response yet.
Never heard or saw a peep of bad info about an Elios brand suit though but the price is nearly double. And you'll still only get 3-4 years out of it if you use it 2-3 times a week - supposedly.
