New stock of the all-in-one will be printed using sublimation rather than screen printing.  They'll still look the same as before, the difference is that sublimation printing becomes part of the fabric rather than the print sitting on the surface of the fabric as it does with screen printing. 

We still have some of the screen printed all-in-ones in stock which we're selling at a reduced price, but if your size isn't in stock please click on the icon for the sublimated all-in-one at the bottom of the page and order from there.
