High loft undergarment colder on deep dives?

[bargeman]

Hi Folks, I am in the market for a new undergarment for a Bare Trilam Tech Dry suit. Was talking to a sales person and he was telling me that the high loft garments will compress a lot at deeper depths and be colder then other undergarments! Any insight on this from anyone that has dove in many different materials of undergarments? First time getting a dry suit, and want to be nice and toasty! Thanks to all.

That's ridiculous. If you keep the same volume of gas in your suit as you go down, your undergarment won't compress significantly at all.

I second that you add air to your suit to compensate squeeze or the water pressure creating a neutral zone inside of your suit. The suit in it's self is an other story it has the water pressure pushing on one side and the air pressure in the suit pussing on the other, there for it can compress.

A laminated suit will not compress, you would lose some insulation with a neoprene suit.

as lynn said-you keep the same pressure in your suit to keep
the loft in your undies and the squeeze at bay
i like layers with 2 pc's-some like the onezies
borrow your buddies stuff and try before you buy?
i like thick...don't like my butt sticking to the ice!
have fun

You just need to translate that into English.

What the sales person actually said is "I have no idea how drysuits work and you should go somewhere else"

As TS&M said, it's just stupid. The entire point of the drysuit is to allow the underwear to remain fluffy as depth & pressure increase.

Fluffy stuff=more trapped air=warmer=more lead.

There's no way around the physics.

Also, don't waste your money on anything that claims to "reflect heat". Nearly all heat underwater is lost via conduction and convection, not radiation. Reflecting heat is only useful for objects that emit substantial amounts of IR energy.

Some super lofty undergarments will not loft. Its similar to laying on a down sleeping bag. Fluffy on top, worthless on the bottom.

Something to consider.
