Hanesmens Beefyt T-shirt, Classic Heavyweight Cotton Crewneck Tee, Roomy Fit, 1 Or 2 Pack, Available in Tall

Will this shirt shrink?

is it true to size???

Are these undershirts? How do they compare to the Hanes undershirts you buy at walmart where a pack of 7 cost $15?

I want to be sure i'm ordering the correct item. these are tall t-shirts correct? and the steel grey shirts come in a 2-pack? thanks
