Under ArmourWomens Tech Half Zip Top

Many of the reviewers don't seem to be aware, but Under Armour makes "HeatGear" and "ColdGear" fabrics. This shirt falls under HeatGear, meaning it protects from the sun in hot or warm conditions, so it needs to be thin and super breathable. For those complaining that it is too thin and not warm at all... that's why. Go for ColdGear if you want protection from cold.This absolutely serves it's intended purpose! I do wish it was slightly thinner though.

Fits great and my wife loves the color

Love this top. I went up a size and I’m glad I did. I’m chesty and my normal size would have been snug.

Was not right color or size

This shirt definitely runs small. I normally wear a large/xlarge, but just from looking at the picture I ordered a size up (xxl), and it's still too small. I like my athletic shirts to fit loosely, and normally I'd be swimming in this size, but it's still too snug. The fabric is extremely sheer, and the arms are tight, so you can't push your sleeves up very high. Not at all the kind of comfortable athletic shirt I would normally wear. Very disappointed.
