An auto-adjusting and auto-drying jacket was worn by Marty McFly, along with a color-shifting lenticular baseball cap, to enable him to pose as his son Marty Jr. in 2015. Both items were produced by Emmett Brown from a large futuristic Nike Footwear bag he carried aboard the DeLorean time machine. The garment had a button on the bottom near the zipper area that auto-adjusted to the wearer and dried itself when wet. As it was performing these actions, it spoke to the wearer on each occasion to let them know what was happening.
