Can you wear jacket under drysuit?

[MoorishK]

in terms of warmth and mobility, do you all prefer weezle extreme plus or tecline 450?

In Minnesota I've seen plenty of Carhartt's under dry suits. Especially the Thinsulate coveralls. I would guess that for the truly cold sensitive, a set of Ice Armor would also work well.

I'm planning to dive dry in winter. Water is about 35 degrees. Will wearing a jacket underneath the drysuit work or do i have to buy a proper undergarment?

Jackets often have unnecessary layers to stop the wind or to provide a durable surface. You only need the insulation. Air volume, that is. It could be fiber or it could be feather, but the latter does not like moisture. Moisture (condensed or otherwise) is pretty much unavoidable.

I have worn fleece and wool though. You might want to do test dives before you commit to a longer stay submerged. Wool has been used historically, so we know it works. You need a lot of it, though.

In 35f water you will freeze without proper undergarments.

Pay attention to your fingers and toes.

I do use white Hestra Quallofil liners and dry gloves (three finger mittens) for long dives. Any ordinary gloves I have tried have failed. There is no need for that canvas or for any wind stopper fabric. Just the fibre with the insulating air inside. Shorter dives I do with three finger wet gloves and woollen gloves (actual wool, not polyamide). Same goes for socks. They need to be warm and wool or fiber are great.

If it’s 35 degrees and you don’t have surface support you have to plan for drysuit failure

A friend of mine suffered a catastrophic drysuit failure in such a temperature. He had to swim 20 meters (60 feet) out of the mine and 30 meters (90 feet) up to the surface. He says it was not easy.

If your drysuit would fail 20 minutes from shore in 35 F water, I would assume you dead unless a chopper rescues you.

and the resulting need to return to your entry point. I’d not do that dive under those conditions with out heated undergarments that work when the suit is flooded and if it’s truely “long” I’d be running redundant heat with a dual thermovalve and 2 batteries

Heating would help. A rescue plan would also. And do remember, that once that drysuit fills with water, it will weigh an awfull lot. You will need enough of backup buoyancy and some means of lifting you out of the water with all that water in your suit.

Check out some of this ski wear I have heaps all top notch

lots of undergarment choices, have a look at the fleece lined windcheaters

At bottom notch prices

You can take the boy out of the money but you can't take the money out of this boy

Nobody should be starting their cold water diving experience in 35deg temperatures. Build experience before attempting. Water at 35F is an extreme condition and should be supervised and assisted by other experienced divers.

I don’t need any undergarments to dive in 35° water because I’m not diving in 35° water, ever. Whatever you use needs to have the loft necessary for it insulation to work, when water pressure squeezes it down it’s not going to work well, you also need enough weight to allow you to add that lofting air.
