I'm another happy DiveTank customer - been diving my nex-gen for 3 months now quite cheerfully. It may be a bilam, but it's one of the few that I've never heard reports of delamination - the laminate seems to be impregnated into the nylon shell quite well. It's a tough shell too - I use it for very rocky (sharp lava rock) entries and have fallen a couple of times, as well as had to crawl out on my hands and knees a couple of times over the rocks, with no harm done to the suit. As noted above the back entry can be a pain, but since I only dive with buddies, it's not a big deal for me... unless I forget to have one of them unzip me before they drive off LOL.
All in all it's a great suit at a great price, and there seems to be a very satisfied user base here on the board for them.
Aloha, Tim
