I have many Under Armour tech shirts which I enjoy wearing, but I really didn't care for this shirt and sent it back.  I ordered the black heathered shirt and got an xl since I like shirts to fit very loose and relaxed, but this shirt was very low-cut and I would not have been able to wear it without a tank or shirt underneath it.  Perhaps if I had ordered a large that might not have been a problem.  The other thing that I really did not like was the trim on the cuffs and the edge of the hood.  The black trim was scratchy - almost like a stiff scratchy nylon.  Without the trim I would have kept the shirt even though I would have needed to layer it, but the trim was a deal-breaker for me.  I didn't even notice the trim before I purchased it, but even if I had, I would have expected it to be made out of a softer fabric like the shirt itself.
