UA finally got the Tall size right!
Size: Small Tall, Color: (001) Black / / White
I'm 5'7" and 130 pounds. This is second time I've bought joggers from UA, size Small Tall, and OMG I couldn't be happier! UA FINALLY(!) got the Tall size right with these...the first pair I ordered about two years ago were supposedly Tall but shrunk up as soon as I washed and dried them. I like them to hit my ankles and not everyone is 5'4". Flattering fit - these sit at my belly button (not too low not too high) and are fitted not bulky. Material is heavier weight, well made, deep pockets, and perfect for Fall & Winter. After washing and drying with no shrinkage, I ordered another pair while still on sale.

Fit and Length
Size: X-Large, Color: (401) Royal / / White
Yeah this fits perfectly. Very soft, the color pops, keeps you warm. I use these under my sweatshirts, cable sweaters, and my flannel shirts. For me it's about the arm length and how well the item contours to the body to help with warmth. Thank you for getting this right.

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.
