ah right... I have an elios that I use for free diving - I do dive with scuba but I've not done so yet in my elios

I love my suit, it's brilliant - really can't fault it. it's a MTM in 5 mill, high waist pants and a closed jacket with integrated hood. its open cell Heiwa with Nylon outer lining.

I think that it would be fine for scuba as the nylon lining will protect the neoprene from the wear and tear that you'd get from the gear (i.e., the BC and the weightbelt), and having looked at the Elios website they would probably do you a suit with nylon outer and probably nylon inner, although you can choose any kind of neoprene you wish. It looks to me that Elios have put that onto their website to attract as wide a customer base as possible.

on your other point on suit compression - yes, they do compress but you can say that of all neoprene, however the benefit of the MTM suits is that they flush less (the zipless ones flush the least) because of the superior fit.

I'd say that a freediving suit would be fine for scuba as well.

I have a 2 piece 5 mill Poseidon suit and a 3mill cheeapie job and they are nice also, but the elios is the best of all of them. the poseidon is good and probably more hard wearing but not much, and not enough to rate it over the elios.

hope this makes things clearer... let me know if tyou have other questions...?
cheers
