Can I use normal clothing for undergarments for single cold dive?

Wear a tuxedo under that drysuit, the jacket and pants are usually wool and silk...both good insulators, even when wet. And, you will look totally James Bond snazzy when you peel off your drysuit to reveal that tux at the end of the dive.

Anybody still doing wool vests etc?

Insulation rating (and lead needed to sink) is: thickness while under compression

Some fleece is so ploofy that it hardly rates at all.

I think that would be fine too.

Beat me to it. Goldfinger pre-title scene. Tuxedo reveal at 2:31.



This was inspired by Peter Tazalaar's real life tuxedo under (swimming) drysuit mission to aid the Dutch Resistance in WWII.

Mythbusters did it as well.
