Doritos 3D's hit stores in 1998 as a hollow, puffed version of the classic chip, shaped into small pyramids instead of the usual flat triangle. The unusual texture gave them a lighter, crunchier bite than regular Doritos, and they came in flavors like nacho cheese and ranch. Frito-Lay discontinued the U.S. version over the following decade, though limited nostalgia driven revivals have popped up periodically since.
