These shirts are great quality.  The material is heavy and the cut is very generous. I am a big man at 6 foot 1 inch tall  and weigh in at 245.  The XL regular size  in this shirt is perfect. This company prides themselves on consistent  quality  and sizing that you can trust. Most cheaper tees that fit out of the box will not fit me after I wash them  because they shrink so bad.  These shirts start out generous and shrink  just right for me.  I like the pocket and the colors are nice also.  They are the perfect working mans shirt.  Amazon shipped them very quick and I am very,  very pleased with this outstanding product.
