The shirt is made with good heavy duty fabric, It fits true to size, but at first it seems to be a little snug until worn several times, then it stretches out to fit better. I run a warehouse and these shirts work well. They have a nice comfortable feel to them that allow's you to bend, lift and stoop without discomfort. The only thing I don't like is the front pocket. It could be a little deeper, to hold pens & markers better, they tend to fall out when you bend over. Pen holders don't fit very well either. Other than that I highly reccommend these shirts.
