Thanks for the recommendations, John and Terry!
While I kind of feel goofy for asking how to keep warm, I can't afford my usual "trial and error" method after spending for this Christmas.
Oh, so THAT'S what that hood was for on the back of my sweatshirts!! LOL seriously, it didn't occur to me till I read it.......

Ah, ok, silk thermals sound like the way to go. Again thanks for the recommendation!! I've never had a need to buy one till now..... And like I mentioned I bought 3 uncomfortable ones already.
Sierratradingpost.com is a favorite of mine, though I've never bought clothes there. Bensbargains.net has "20% off" coupon codes for sierratradingpost.com right now, makes the deal even sweeter. Thanks for the recommend!
Thanks for the info on Devold! I had problems with their website, so I requested a catalog.
I'm hoping father Christmas drops off a Rev Indoor for me!
Thanks for the info Terry! It will help me stay warm and stay flying. Best wishes, I hope you can do the same
