As one may expect from their HeatGear, the UnderArmour ColdGear manages perspiration really well. Occassionally, what I encounter in the field is warmer than predicted or the workload is more vigorous or extensive than usual. I'd guess that you already know the risks of sweating in cold weather.
All my winter beanies and base layer down to the ankles is UnderArmour. I may have to buy stock in this company. I recommend the #1,#2, & #3 base layers, I use them in combination to give me  4, 5, and 6 equivalents. This is covered with appropriate layers of easily removed fleece, giving me all the warmth I need in a North Dakota winter without sacrificing breathability, flexability, or being held back by a weight of clothing.
