Normally I would never ever buy clothes on the internet.  But now with the high cotton prices, all the t-shirts that I see in stores are made of tissue paper.  Try taking a batch of t-shirts out of the washing machine.  Old t-shirts are heavy with water while new t-shirts come out as light as they went in. So I ordered various brands here on Amazon.  Dickies are nice, but still too light.  Hanes Beefy-t's shrink a little too much and its hems constantly and annoyingly fold up.  Fruit of the Looms heavy's have the same hem problem.  Enter Riggs Workwear.  The material is heavier than even old t-shirts that I own.  Why are these called Workwear? I don't know.  They look fine for everyday wear.  The neckline is tighter than others, but that matters only while dressing, not while wearing.  The pockets are nice and sturdy.  They hang a little long and they seem a little larger than the size indicates, maybe that's to hide the "plumber butt" and allow for undergarments. I know you can't do this on the internet, but if you're in a store try a medium if you usually buy large. I highly recommend this t-shirt.
