Since my down or polyester jacket or snow suit won't be getting wet during a wave
flight, I've gone that route. Don't have anything with wool in it, and thermal
underwear, "street clothes", and an down or polyester snowsuit keep me warm. It
helps a lot that I've fixed all the canopy and vent leaks, and that I usually stop
at 0 deg F on the climb.
