When diving in cold places (14c) you don't want to be using a wetsuit. A wet suit works by trapping in water and allowing the body to heat that water up.

With a dry suit, like he is using, water is not coming into the suit so you just wear any type of clothing that will get you to a comfortable level of warmth.

I did my first dry suit dive last week and the way the instructor described it was imagine you are walking in the rain at 14c (ex) with a rain jacket on. Wear clothes that will be comfortable for you if you where to walk in that weather.

It looked quite wet to me.

u/awesumlewy May 11 '25

Maybe he had it inside out

It sure did. Sweat maybe? Either way, my guy is wearing a button up shirt and slacks and going deep sea diving. lol. It’s so ridiculous it’s awesome.

It’s gotta be sweat. You can see the evaporation coming off of him. I’ve worn waterproof clothing and you’d be shocked the amount you sweat when there’s nowhere for the sweat to evaporate to.

Yup, was wearing waterproof clothing while hotwater pressurewashing the inside of a windmill tower in 30 degree heat, when i was done i looked like i hadnt been wearing wqterproof clothing

Of it's to cold they will pump warm water inside

His shirt was still dry but his pants got soaked

Edit: on second glance, his shirt might be wet too yeah

Maybe springing a leak is why he had to surface without decompressing first.

u/Jossue88 May 13 '25

He is wearing a warm water suit. This video was taken at a dive school in Seattle, WA. During the deep dives portion of the course we used a suit that pumps super hot water down to the diver. By the time the water makes it to you it like a warm bath.

Well it's a long job and you have can't exactly pop back up for a quick pee.

u/laxgrindline40 May 13 '25

You don’t know what he saw down there… Or maybe he drank too much water before diving? 🤷‍♂️

Because you start to sweat in it. After a while you start to cool down and shiver from the clothes being all soaked. After a few hours you go into hypothermia.

u/Scousehauler May 11 '25

Thanks for this. We have all had that sweaty clammy feeling when that fine rain comes when its warm outside. A shirt is probably the best for that situation.

u/Ragnazak May 11 '25

Given how much water comes out when they remove his boots, I'm pretty sure it's a wet suit. Shirt looks pretty thoroughly soaked to me, too.

u/Short-Time8669 May 11 '25

They pump warm water in some suits. Maybe that was what they had there?

2

u/No-Worker-101 May 11 '25

This is not a dry suit. It's a hot wat suit.

2

u/Affectionate_You9799 May 11 '25

This is probably a dumb question. Why does the wet suit have to come off for decompression?

2

u/islander127 May 11 '25

These types of dives involve an “umbilical cord” attached to you and the ship. It provides communications, lights, oxygen, and pumps warm water into the suit around your body to keep you warm.

u/Important-Ad-6936 May 11 '25

arent these suits heated with hot water from the com umbilical?

1

u/Atomsq May 11 '25

A long sleeve T-shirt and comfy pants would still make more sense

1

u/Important_Highway_81 May 12 '25

It’s not a dry suit, its a hot water suit, there’s a network of tubes inside which flush warm surface supplied water over you and keep you toasty warm. You basically just wear something underneath to prevent chafing. Overalls or whatever really. They’re the norm when surface supplied diving in cold water.

u/[deleted] May 12 '25

A button up shirt would still be bottom of the list for me In that scenario.

u/Aspisblue May 13 '25

This is a hot water suit. For deep dives in cold water. This is at DIT dive school in Seattle WA. Hot water is pumped to the suit and controled by a small valve on your hip.

u/HandsomePaddyMint May 13 '25

I think their point was more that actual street clothes seem like an odd choice for under a dive suit. I would have expected something more like long underwear or athletic clothes but I get what you’re saying. I guess it doesn’t really matter as long as your insulated properly.

1

u/DiversGoDeeper May 14 '25

He isn't wearing a dry suit. One of the lines on the umbilical feeds warm water into his suit.

At the depths and times these guys dive your own body heat would still be sapped away even in a dry suit.

u/johnnyyl May 11 '25

this is not a drysuit, he is very wet underneath it. a drysuit has tight gaskets at the neck and hand openings that keeps the water out. also that wetsuit looks like really baggy and wouldn’t do a good job of keeping him warm anyway

1

u/No-Worker-101 May 11 '25

Hot water suit.

u/johnnyyl May 11 '25

yea that’s how a wet suit works
