The size XL fits exactly as expected. I usually have L, but, if you take in sports shirts a size larger so that the shirt is airy. That is the case with this customized tank top. The fabric is comfortable and flowing. It feels very nice and cool on the skin. Normally I wear rather Shirts V-Neck because often arises in round necklines unpleasant pressure on the neck. That's not good so.Das like me in this top. On the positive side is that the shirt dries very quickly and is not as strong sticks during perspiration on the body, such as cotton shirts. The processing seems to be very good. The seams are straight and look stable. Overall, a great top for sports in the summer.
