These tees are good quality, they're not the heaviest ones out there but nothing like the thin cheap junk you find in stores and for the money they're very good tees.  At first I tried the XL size because that's the size Russell Athletic tee that fits me..... It was a little too big for me even after washing. That's OK though because I can where the XL for just kicking around the house. I then ordered a large, perfect fit and very comfortable.... I'm wearing it as I type this. Now that I know the right size I'm ordering 4 more in different colors. I recommend these pocket tees they should last a good long time. BTW the forest green looks much better in person than the on-line picture.
