I've got a Seaskin that I bought secondhand; it has the zippered pockets. They're secure, but that's their only real virtue. I don't groove on them a lot.
1) The zippered pockets are kinda small. I carry a 6' DSMB and a 150' spool in my right pocket, and those two items take up pretty much ALL the room. I have zero idea how
@Boarderguy manages to fit anything else. (Admittedly, mine is a secondhand suit cut for a toothpick-dude and I'm of a more substantial build. Maybe my burly, buffed-out, trunk-like thighs are squeezing the pockets from the inside?
)
2) The zippered pockets aren't very dryglove-friendly. I have fairly large hands (XXL gloves) and when I have drygloves on, which is most of the time when diving a drysuit, I can't quite reach the bottom of the zippered pockets. If something's fallen into the depths, then it's stuck there until I get out.
3) The zippers can be a challenge to manage properly. I've ended up with a mask or my backup light halfway hanging out because I couldn't get them stuffed back in properly, couldn't get the zippers redone, or both.
Also, one of the zipper pull tabs broke off a year-plus ago. I replaced it with a split ring (like a key ring), which works well but isn't exactly optimal.
I ordered the big ol' Expedition pockets on my new Seaskin, which should be arriving next month.
