These are perfect summer t-shirts for people that actually wear tool belts,they fit like they are supposed to,a Dickies 2x will fit you like a Hanes 3x,not saying that's good or bad,nor will I say Dickies run large,to the contrary,I will say Dickies fit right and out last many pricier brands the necks, sleeves, and waists of these t-shirts are suprisingly good,plain and simple you will not find a better t-shirt under $10. These are the only T's you will need for work, I wear 2x and 3x in the winter for a nice deep tuck in around areas I like to keep warm .
