I never go into WalMart for many reasons, but I would bet that their fabrics are the same as their other goods. They force ccompanies to make say, Hanes socks, with a lower thread count than they use for Target, for example, which is why WalMart clothes rip and wear out. I bet their fabrics are made with lower thread counts and I wouldn't be surprised if they use dyes that are harmful, because all of their stuff is made in China.
