These Gildan 6.1 oz T-Shirts are excellent.  The material is just right and definitely not like cheap see-through T-Shirts you see about everywhere these days.  They tend to fit somewhat large so it's best to just order the size you wear, especially since they don't seem to shrink after washing/drying. The pocket is very sturdy.  The overall quality is excellent.  I've bought four of these in different colors and will be buying more.  They are built to last.
