Thanks Pat,
I suppose I'm addressing most of us who have inappropriate perspiration, often triggered by the cold. You get cold, ya sweat, ya get a chill, and it all starts over, and drives the pain. I don't have much experience with lack of perspiration.
Heat went off in my apt. last nite, woke up around 4AM, it was 55 in here. Called, got a call back @ 9AM. Still no service, so I had to turn on the gas burner for a while, (VERY Carefully). just a side story, but, as soon as I had a cup of warm tea, I was soaking wet with perspiration, while it's still cold in here.

Back to the Patagonia Capilene, the silkweight might be very comfy for you...

Be Well,

Pete
