It works great at getting the perspiration/moisture away from your skin which in turn makes you feel a lot more comfortable. I used to wear cotton t-shirts under tons of layers and a huge parka, I'd get warm, sweat a little and thenI wouldfeel cold. Now it is just some under armour and some fleece and a weatherproof outer jacket and I am set. The moisture wicking was huge for me. The gloves have been a life saver. My wife got me some stuff from LL Bean that is similar to Under Armor but a fraction of the cost for work and I think it works about as well as the UA.
