The Hanes Beefy T comes in pocket T style, don't know about a tall version.
I like my T-shirts to be made with heavier weight cloth and Hanes is consistently the heaviest in pocket tees.
Land's End offers tall versions of pocket tees.
Last few years, I have preferred Fruit of the Loom sleeveless t-shirts (not the wife-beater style).
Walmart offers them only seasonally in the spring, and my wife grabs them up when she sees them.
I have the next generation of tee shirts in reserve when this generation wears out.
