Tips for being warm in a drysuit?

[Oldpirate]

I switched to an AGA full face mask and the difference is amazing. Very warm all the time. (DUI Signature series drysuit, dry gloves, dry hood too). I still use my old Viking "jumpsuit" underwear though.

For helping keep your body warm...I found some thermal underware at the Chicago Ski show awhile back called zyflex. This stuff is great, I used it for my dry suit cert dives under the dry suit thermal ware and I was very toasty. I really like this stuff check out www.zyflex.com for more info (it only available online)
