Tight but stays in place, comfy and keeps you warm
Size: Medium, Color: Charcoal Light Heather (019)/Black
I liked this shirt because it keeps me warm when I'm outside even at negative temperatures, I can work out comfortably in it and the sweat dries out soon; also, the interior of the shirt is made of a very comfortable material.
I don't like that this is very tight, cool if you want to use it under your usual sports clothes but if you want to use it as is I would suggest going up a size.
I use this shirt almost every day to work out during winter time, I've washed them several times and they still feel as comfortable as the first day.

Perfect for running!
Size: Small, Color: Black (001)/White
None of my running clothes make me feel as sexy as this underarmor does. It is so soft on the inside, which is an upgrade from their old version because I found one at the thrift store that is really scratchy. It has been through a cold wash and the dryer multiple times at this point and it is still holding up. The size is true. The material thickness is perfect for me between 45-35° F. And again with layers between 15-10° F. But I look forward more to my runs that I get to wear my underarmor. Nothing makes me feel more confident on the trail. And I love love love the turtleneck. I got all black because that is my favorite color to wear when I run and it looks perfect. It is a true black.

Great all around and durable. Will last a long time.
Size: Large-X-Large, Color: Black/Anthracite/White
Great hat for being lightweight yet holding the sweat it needs to while also being cooling with the air vent holes. Perfect velcro that moves and does not collect junk in the wash. Durable and is long lasting. Have used for many months and wear a visor daily. It is my favorite.
