What undergarment for drysuit are you wearing?

[FF / EMT]

Halo AR, but it doesn’t do its job if your suit leaks…
My next thermals will be a heated suit, probably a santi

Tuck a handwarmer under the ballsack

lol, I do hand warmers in my gloves in the winter, that’s brutal diving, not sure why I do that, no mosquitos though

I have a Fourth Element Arctic 1-piece suit. It's great from 50-55 degrees (which is most of my diving) with my laminate drysuit, but starts to feel a little cold in the high 40's. It does a really good job of keeping you warm through little floods- I left my thumb loops out when I switched to neoprene gloves from my dry gloves right before a dive; and the main thing I noticed wasn't cold, but that my trim was super weird. But both sleeves needed wringing out and some air dry time before the next dive. I also picked up a clearance Arctic Expedition suit, which is noticeably thicker than the regular Arctic, and probably stays comfortable down to 45 but haven't wanted to figure out new weighting. So, I haven't used it yet. The expedition has been discontinued for a few years anyway. They probably thought it overlapped too much with both the Halo and Arctic.

Diving in European freshwater lakes on average.
Winter temperatures are down to 4C or around 40F.
Diving in a DUI Flex Extreme 450 trilam drysuit, combined with a DUI XM250 undersuit. A base layer of ski thermo long sleeves and trousers.

My bioprene prevents the use of an XM450 at the moment.
In the winter an added heating vest makes the dive more comfortable. (thermolution)

I wear the Fourth Element Halo AR in the Florida springs/caves (72 year round), and still get cold, but I’m an outlier when it comes to temperatures - I always run way cold.

Weezle Extreme for Lake Huron, switched from DUI 250 thinsulate jumpsuit. Both are similar in terms of warmth, both dry and not so dry, but the Weezle is much better for flexibility. Had to add 2 pounds for Weezle. One hour dives at 46-52 are ok, toes get cold, 56 is very comfortable. Trilaminate suit.

In the Great Lakes I have used a DUI CF200 dry suit with either a weezle or FE artic and a x core vest. The combo has worked well.

Depends where you dive. Where I live water varies from 6-15C depending on time of year and salt vs fresh. I bought a set of Arctics years ago when everyone was raving about them and most of the time I find them too thin to use as the primary insulation layer and too thick to use as a baselayer. That's with a DUI crushed neoprene suit. The only diving I really use them for is sump diving because they're better for caving in than a standard thinsulate type undersuit. Most of the time I just use them as a baselayer for sea kayaking in winter.

I use an Otter 200g undersuit, mostly because it was free and it is warm. I keep thinking about buying something fancier and more modern but it does the job and I can just vary the base layers with the seasons.

Hell I use Fourth Element Arctic one piece with my drysuit for diving in 70 degree caves in north Florida. . However I did 36 years of Great Lakes wreck diving before I got smart and moved to Florida.
