The quality of Under Armour Shirts is very good with security! I myself possess now 7 piece of it - short-sleeved and best selling in the area in shops! Unfortunately, it is the size really difficult! A shirt has the cut of XL although it is indicated with L. Has the other Shirt with indication of the L-section so small even at the XL even the collar is tight so the simple but buying and ordering process on Amazon, is very difficult. Here important to note that this shirt is cut here very large and prefer a smaller number should be ordered. Only a small tip ....
