I've been researching wetsuits, have come to the conclusion that I will probably go with a custom sized, if I can get the money together elios or the suits P.F.I. sell would be ideal, but I found a site diveskin.net that sells custom sized (oceanos) freedive suits, heiwa neoprene-slick outer nylon inner for 159.00 usd, I know open cell inner would be ideal but has anyone used this suit? is it good? junk? I dive arms forward with a monofin, are the shoulders very flexible?
