I too perspire a lot and while skiing hard in cold weather. Following are some of the solutions I’ve discovered over the years (most of which have been mentioned here and there throughout the previous posts) that work for me. Emphasis here on “works for me” (we all have different heat regulators) and applies to skiing aggressively. Adjust accordingly when playing on the hill with kids or skiing with beginner friends.
Never anything under the helmet and vents always wide open. Seems I can’t ever get rid of heat and moisture fast enough while wearing a helmet. At times I remove helmet on the lift regardless of temperature if it’s not snowing. Just try to not let the damp hair freeze or it’s difficult to get helmet back on (don’t ask me how I know this)
I no longer wear a face mask or a neck gaiter even in a blizzard. Both impact moisture management to much with goggles. I simply vary the zipper on my jacket to completely cover my chin on the lift (with jacket hood over my helmet) versus hood down and opening the zipper appropriately on the way down.
Pit zips always open.
Light weight high quality breathable long underwear (e.g. Patagonia Capiline or smartwool products). Can’t emphasize enough the need for light weight. Every time I’ve thought “this blizzard requires the heavy weight stuff” I end up regretting it. Sure I’m warmer initially but eventually get too hot and of course the heavier stuff can’t breathe as well then everything gets damp. Also found that Capiline briefs mitigate the sweaty feeling.
And most important, the midlayer. Always a vest. Allows the sweat to escape from underarms. I use a light, medium or heavy weight vest depending on conditions. Sure the arms get cold on the lift with only a shell covering them but I’ve found that’s the price I have to pay to minimize the perspiration. (I’ve tried arm warmers but they were a pain and I gave up.)
Bottom line, for me, is warm feet (starts with a heated boot bag), warm hands (good gloves – takes some experimenting) and a warm core (i.e. appropriate vest). Then I can deal with a few temporarily cold body parts in order to mitigate the sweating. And of course I’m hopeful that over the years I’ve made slight progress towards that “effortless flow” state we’re all working toward. (Though given the rate at which I still sweat, probably not the case).
PS Couldn’t agree more with the timing considerations mentioned by Pat in post #28.
