Review on Under Armour Men's ColdGear 4.0 Base Leggings by Kofi Wills

As many other reviewers have said the 4.0 is very warm and works best when you are still. I bought a Series 4.0 top and bottom for hunting at the end of the standing bow season. The material is very comfortable and the compression of the material against your skin is not unbearable so you can't wait to take it off. The old UA series was always very tight and became uncomfortable during the day. My previous set of UA base layers held together perfectly for several years (5+) until the elastic around the waist finally broke. The old adage says you get what you pay for. Buying a cheap base layer will only limit your ability to stay focused and stay in the woods.
