Drysuit Undergarment?

[mick allein III]

I own a Bare Trilam and have been diving it for 3 years. To save money I use a variety of layered underarmor and fleece underneath. I have been very comfortable in water in Themis 40s. But recently spent some time in 38-41 deg water and became chilled. Any suggestions on good, affordable thermal protection. I'm okay with suggestions on layering better etc. I don't have tons of $.

How long does it take to become chilled in the 38-41 degree water? I become chilled in my Thermal fusion in around 45 to 50 minutes or so.

Not long 15-20 minutes

Not having "tons of money" makes it hard. I'm super sensitive to cold so for me in those temps it'd be a heated vest. I wear under armour and a North Face base layer, with a merino wool top on top of those two with a Santi BZ200 and get chilly in water in the mid 50s.

I also wear a full 5mm in the tropics and don't get hot.

Might want to check ebay. You can find some no name fleece undies on there. I use Under Armor cold gear layered with my DUI Polartec undies and I start to get chilled in the mid 30° range. I think some of my chills come from sweat also.

I use a 300 gram polartec inside a 3mm neoprene suit and that keeps me warm in upper 30's temperature. I have been down to 92 feet in this set up and did not feel a thing.

Would thinsulate keep me warmer? Possible.

Do I feel the need? No.

Would insulate be a better choice in case my suit floods with water? I would have to compare by first flooding my suit with cold water while wearing thinsulate and then do the same while wearing polar tec.

Am I willing to do that? No.

Are the people who sell thinsulate willing to give me a live demonstration of this stunt in mids 30s water? Nope.

Should you buy it? You decide.
