I own a Signature Series CF200X and it does not come in pieces as you say
It's literally in pieces when you order a signature series or special production. Those suits are custom fitted to your measurements, so they actually cut pieces according to that size and then put them together. I didn't mean that you get your suit in pieces.
Special Production: Custom fit/sizing, no additional pockets/features/addons included (I think)
Signature Series: Custom fit/sizing, 2 additional pockets, kevlar or CF200 kneepads, and included hood
Ordered FLX50/50 signature suit about six weeks ago, spokewith DUI on phone about pockets ect, nothing was mentionedabout any kind of zip seal
The new system isn't really geared towards the rental community, just so happends it meets that particular need. The wear and tear on rental suits is VERY high, so this is a much easier way to fix the problem, rather than decomission the suit for a few weeks while it is sent to a scuba repair facility or DUI for repairs. They were in testing/prototype with the seals until DEMA, which they had officially released it as one of their products, thats probably why they did not mention anything about it.
It's overall, more of a convenience for any party that uses it. Serious tech divers used to have to carry seal kits, if not an extra drysuit with them just incase a seal busts. Now this is uneeded as long as you carry extra seals around with you, just a simple pleteing of the teeth and you're good as new.
