Adaptive vents

Abstract

Aspects herein provide for an article of apparel having one or more vent systems that dynamically transition to an open state when the article of apparel is exposed to an external stimulus. The vent system includes an adaptive structure affixed to the surface of a textile proximate to a slit in the textile. The adaptive structure, and the surrounding textile, changes in shape and / or dimension when exposed to the external stimulus causing the slit to dynamically transition to an open state and creating a vent opening. Once the external stimulus is removed, the adaptive structures and the underlying textile return to their pre-exposure dimensions causing the vent opening to transition to a closed state. The adaptive structure can be configured and positioned relative to the slit so that its effect on the shape and dimensions of the textile on either side of the slit are different.
