I purchase the classic shirts for my husband and the lighter weight also. He conservatively has in excess of 100 that I have ordered him over the last couple years. Always ordered classic in XL which have been fine. But the lightweight ones seem to be not on the same size standard, the XL are too large and the L run very small. My last order, 4 lightweight size large, I have had to find homes for. Darling graphics but it has become too difficult with the sizing issue. Too sad, he teaches Obedience for our local club and has them on daily & have always been a hit with students.
Good quality shirt with nicely printed design. Sizing is good as well
