I work construction all year round. Winters can be hard sometimes. Hate feeling bulky with to many layer of clothing that don’t keep me warm. Having the proper clothing makes all the difference. 4.0 Under Armour are great.

Exactly what I expected
The fit is perfect and it is very warm and comfortable for my late season bow hunting. And .... I got it on sale which makes it even better.

After reading reviews for the NEW 3.0 and 4.0 Base I am NOT going to buy any
I have the 2.0 base layer version and i have been extremely happy with them. I came back to find some more and noticed the new 3.0 and 4.0 versions and decided to read the reviews.... After reading all the reviews and i am going to hold off on any more purchases of this merchandise

Outside work
Simply the best. I work outside and in the cold it's the only thing you need. I normally would wear bib overalls. To bulky hard to move around in. Put these under your work clothes it's all you'll need. And maybe a hat

Toasty Warm
I need a warm base layer for an upcoming trip to Antarctica. I ordered one of the new Base 4.0 Crew to try it out. It has a snug feel and keeps me toasty warm, even more than my other UA base layers which I like and wear a lot. I ordered a second Base 4.0 and both of my new tops will be part of the 33 pounds of luggage I’m allowed to take across the Drake Passage to Antarctica. I plan to stay comfortable riding from ship to shore in the open air zodiac boat.

This product has great features to keep you warm.
The Coldgear base 4.0 Crew shirt works great to keep you warm. I use the shirt for a base layer when Referring soccer during the winter months.

Fit great for a bigger guy around the waist. I'm 235 lbs and it fits perfect Very comfortable and thin but doesn't keep me quite as warm as I expected.
