    I know you were asking tbone, but I think the answer is yes. The fibers take up space. A suit is poofier because the fibers take up more volume. The more high-tech fibers are thin, or even hollow, and so take up less volume. There is better insulation because more volume is occupied by air and less volume is occupied by fiber.

    it depends on how thick said poofy undergarment is. It will ultimately compress to something similar to the density of the felts but when it does that, it may not have the same insulating properties so will require more gas in the suit. Minimum bubble size is what is determined by the packing density of the undergarment. I.e. you have a lot of thick poofy stuff, if when compressed it is still thicker than the felts, then it will require more gas and will be warmer.

    @Lorenzoid not exactly. A suit is poofier because the fibers are not woven/knit/locked into their place and have a high crimp value to make them spring out and are just stuffed into a shell no different than a pillow/comforter/sleeping bag They typically use the same fibers believe it or not. The felted type fabrics are woven/knit into place and then napped to form the felt. They are not allowed to move around

    My deep class was at the local quarry's deep hole this weekend. Temp was 46F at 80ft. I was in my new 5mm. Had 5mm hood, gloves, boots. I was toasty.

    I'd kill for that kind of cold tolerance lol.

    What's funny is that the gal instructor and I were in 5mm, and the two guys were in 7mm. Women are tougher! :rofl3:

    I also have some extra bioprene. :D

    I'm convinced women's air lasts longer too!

    I did the deep dive a couple weeks ago. Went down, saw the rickety pallet, lost sight of the rickety pallet as everyone else made it down, and was happy to head up to the safety stop afterwards lol. For all my complaining, I ended up having to go back down to try to find my buddy's lost weight pocket lol.

    I'm something of an air hog at this point! :wink:

    By "rickety pallet," I assume you mean the platform? Didn't seem rickety to me! At least the buoys were both back in place (one was missing recently), which made the PVC bars every 15 feet list sideways like they were drunken, or so I'm told. We did our safety stop on the bar under the south dock (there's one under the west dock, too), as we went on a tour of the wall after we came up out of the hole. I'm glad the black sulfur layer at 60ft, which turned the hole into a dark as night pit, wasn't there. Viz was about 10ft, but the sun was out so we had some light.

    Ok maybe rickety was a bit rough, but those newer aluminum platforms look awesome comparatively. I think our plan was to do something similar, but we had one guy lose a pocket and someone else got a little freaky and bolted, so we just went up the buoy line and did the ss there. The bright side was getting to practice with my dsmb and completing the ss on it since most of everyone else was bunched up butts to nuts @15' on the buoy.

    Someone got freaky and bolted from 80ft? Sheesh...

    I think it was more the bad viz than the depth that got to her.
