    Worth it.
    Size: Small, Color: Black (001)/White
    Living in North Dakota, staying warm is invaluable. UnderArmour Cold Gear is the only base layer the provides warmth, KEEPS warmth, and protects from the unforgiving wind. Every winter I go on the hunt for thermals, layering options and I always find others to be saggy or incredibly tight, either way, once I begin shoveling or snowblowering, and sweating, other products become soaked, sticking to skin, unbreathable and quickly your sweat stuck to your body under layers in now creating a cold,chill, freeze to your body, and on a -10F day, it can become a dangerous situation. I honestly was hesitant to purchase UnderArmour, I felt it was too hyped up or paying for a name. BUT IT IS NOT. UnderArmour isn't a name, it is a company that has made the highest quality base layer, warmth, breathable and it really wicks sweat away; I may not know how it does it, but it works! For sizing, I ordered a small in the women's longsleeve/turtleneck black coldgear. I'm 5ft and roughly 110lbs. I like the fit, it is meant to fit your body. I probably could wear an extra small, but I like the sleeve length in the small and it fits very well. Stay warm folks!

    Great cold gear
    Size: Large, Color: White (100)/Black
    Warm, very comfortable. I wear these all winter. The neck can be a little tight and the cut is definitely fitting. Its got thin like fleece on the inside that keeps you warm.

    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.
