O-ring once bubbled...
I have 300g polarfleece and get cold in weenie water...what are you guys doing for hoods/gloves? Maybe it is my head or hands that are making me cold...
For what it's worth, I get cold wearing the same underwear as UP (mine's a 300G one-piece single layer). His are two-layer (inner being micro-fleece), which is similar to my wife's setup. I'm currently using the botoom layer of polypro, but have considered getting a set of Chilly's (tm) microfleece underwear to see if it would keep me warmer, since my wife who is typically *way* colder than me stays warmer in her setup than I do.
I'm also using the same DCI gloves, and they are the best. I have to say that my diving comfort increased immensely in cold water with the addition of the gloves. Previously, a 15 minute dive with my 7mm neoprene gloves in 45-60 water was the most I could do before my hands go so numb I couldn't hardly use them. Now, I dive them in *all* water, from 36-75 (it doesn't get any warmer than that around here).
I'm using a 5mm White's zipped hood which tucks into the collar of my DUI, and the zipper makes it really easy to don/doff. I've been considering an upgrade to a 7mm hood, or perhaps a blown-nitrogen neoprene one without the zipper for *really* cold water (ie; ice-diving).
Basically, from about 35-50 degrees, even with the 300G fleece and dry gloves, I'm still chilled about 20-25 minutes into the dive. I've added additional layers, and it helps somewhat, but I end up having to add a bunch of air to the suit, and I'm getting really constrained so much that I can't reach my valves anymore, so I need to re-think things.
I suspect one of my problems is the drysuit. The CLx material gets pretty stiff when the water is cold, so dexterity suffers. I've considered getting a 400G thinsulate garment, but the price is prohibitive.
Bottom line is that the dry gloves helped me out immensely, but I'm still getting chilled. I haven't (yet) found a good solution that doesn't involve either:
* Adding a bunch of air, making for very floaty feet at the end of the dive.
* Adding a bunch of layers, making dexterity difficult.
It's possible that a better hood is the ticket, although I find that the back of my head stays almost dry, so it's not likely that the seals are bad.
I'm sure this doesn't help you much, but it's another data-point...
