snapback

Snapback is a term used in various fields to denote a rapid return to a previous state, shape, or level after a disturbance.

In fashion and apparel, snapback refers to a baseball-style cap with an adjustable back closure that uses a snap-fit mechanism, typically plastic or metal. The closure allows the cap to fit different head sizes. The term originated from the plastic snaps used to fasten the back strap; the style became popular in streetwear and sports culture and remains common in cap designs.

In materials science and mechanical design, snapback describes elastic recovery, where a component deforms under load but returns toward its original shape after the load is removed. Some products incorporate snap-back mechanisms, such as springs or flexible rims, to automatically reset to a starting configuration after use.

In economics and finance, snapback denotes a rapid rebound in prices, profits, or economic indicators following a downturn or shock. The term is often used to describe short-lived declines followed by swift recoveries and can influence market expectations and policy responses.

In electronics and related technology contexts, snapback can describe a transient response in circuits where a parameter returns to baseline quickly after a surge, or a protective or reset behavior that restores normal operation after a fault.
