The wearing comfort I can because of the softness and lightness of the fabric only be described as very pleasant.
Processing I find very good, since there is no untidy seams or projecting thread ends.
After repeated washing the fit has not changed and the shirts still look like new.
On the left chest is the typical UA logo and on the back is directly under the Halssaum also a small Under Armour lettering.
The size specification I feel as realistic.
The shirts are made of 100% polyester and produced in Honduras.
Whether any of this shirt line are other (different) manufacturing countries I can not say unfortunately.
