IMHE, Neoprene is waterproof unless it is not made correctly.

Herein lies the problem. You base your statements on what you have seen
and
then generalize that ALL neoprene is closed cell. Maybe all of the
paddling
and scuba related equipment does all use closed cell neoprene but the
statement that open cell neoprene doesn't exist or is a result of faulty
manufacturing is simply wrong.

Mea culpa. I should be more specific. However, in the context of most of
our discussion, the neoprene is closed cell. Open cell is not as common.
The only open cell neoprene I've seen and touched has been in mouse pads.

Let me put it this way: Closed cell neoprene that isn't waterproof is not
made correctly. Sometimes you don't care (zippers and seams on paddling
FJ), sometimes you force the issue (lotta sliced holes in neoprene
paddling socks).

Do a google search for open cell neoprene. Then do one for free diving
wet
suits.

Free-dive = neutral bouyancy if possible, hence the open cell.
