Tato Skins is a brand of thick, dark, seasoned potato chip-like snacks available in several flavors (such as baked potato, Cheddar & bacon, sour cream & onion, and steak & potato).
Tato Skins have been manufactured from their inception (around 1987) by Wabash Foods in Bluffton, Indiana. They were once marketed by Keebler but changed hands to Poore Brothers, which also markets them as T.G.I. Friday's Potato Skins Snack Chips.
They are similar to Pringles chips in that they are made from dehydrated potatoes and have a single shape.
Each chip has a light-colored side meant to represent the inside of the potato, and a dark-colored side meant to represent the skin.
