Wetsuit under dry suit?

[Humuhumunukunukuapua'a]

Wrong. The water IS the heat loss. The wetsuit minimizes it. I said it. Your quoted article said it. Others have said it. You just won't belive it.

The water does nothing to prevent, minimize, alter, reconfigure, fold, spindle or mutilate heat loss. It is, quite simply, a SOURCE of heat loss. It DRAINS your heat. Nothing more.

But these really are creative arguments against the nature of physics...

I agree with you Hum. I have stated several times that it is a heat drain but I repeat my question though...Would you rather have the original trapped water layer or a new one constantly flowing throught the suit?

Maybe the water temp was warmer than the air temp. Throw in some wind and evaporative cooling and your feet will feel much colder above than under water.

I did a few wet dives lately where the air and water temp were similar and I felt much colder at the surface than underwater. This was due to the fact that the wind was kicking and cooling my wetsuit above water, but not below.

Yeah, and thinking about it, my feet were on plain ice. And under wetsuit boots, the neoprene layer is thiner and it's more a rubber layer or something which is not really a good insulator. Anyway, I dont do that kind of diving anymore. I prefer to do it naked but I keep my hat on to prevent thos heat losses:05:

seriously, I usually wear a drysuit:10:

suggest you try one of these:

1. I'm wrong.
2. My assumptions and assertions are flawed.
3. Thanks, I stand corrected.
4. Uh, I thought I understood, but guess I don't.
5. Never mind.
6. I'm wrong.

To me...saying the water has involvement is like saying that it's the *air* inside a winter coat that keeps you warm...not the coat itself. That statement is obviously absurd...so why don't people understand the wetsuit thing? Who knows.[/I]

heu... hum... actually... in a way... it is:11: In fact, as much water is a good heat conductor, as much air is a bad one, the worst in fact. That is why we dont press on house insulators and keep it fluffy. A good suit or sleeping bag is a one that keeps humidity out and a good layer of air trapped. It's the principle of window glass double layered so there is air trapped between the two layers. I know, it's freezing to death right now outside with a good wind and a snow storm. But my windows are still warm.

But I know, there would be no insulation if there was no coat so ok, the coat insulates you:05: and I dont want to start another argument:05:

So what is the consenses?? Would a wet suit keep you warm under a dry suit?

Is anyone willing to try it out?? I think a few of us should an report back to settle it once and for all. I don't have a dry suit so I can't try it, but i'm curious.

And by the way, aren't the suits that downhill skiiers and people who do the luge and bob sledding kinda a neoprene like material??

Its a stupid idea.

maybe but it's for speed cause it cuts the wind friction

I did say my opinion jaycanwk, do I have to quote myself?:05: :05: :05:

All of this made me realize that a wetsuit under a dry would not be efficient for one reason: neoprene is impervious to water. So you will sweat in it and the water will stay close to your skin, therefore draining your body heat. That is why cotton is not a good undergarment (in a drysuit or if you do winter sports, under snowcoats) and lifa or polar is much better 'cause they keep the water away from your skin.

Gosh, all that blabla finally got usefull

Been there, done that, check earliest posts in thread for results of my experiment :biggrin:
