Apparel with dynamic vent structure

A textile comprising:

• a slit extending from a first surface of the textile to a second opposite surface of the textile, the slit comprising a first edge, an opposing second edge, a first end, a second end, and a longitudinal axis extending between the first end and the second end;
• a first overlay film structure applied to the first surface and positioned adjacent to the first edge of the slit;
• and
• a second overlay film structure applied to the first surface and positioned adjacent to the second edge of the slit;
• wherein when the textile is exposed to an external stimulus, the first overlay film structure and the second overlay film structure undergo an increase in dimension in at least one direction to cause the slit to transition from a closed state to an open state with the first edge and the second edge of the slit extending in a first direction away from a surface plane of the textile.

A textile construction comprising:

• a first panel of material having a first aperture extending therethrough;
• a second panel of material positioned adjacent to the first panel of material, the second panel of material having a second aperture extending therethrough, wherein the first aperture is at least partially offset from the second aperture when the textile construction is in a closed state;
• and
• an overlay film structure affixed to and extending across a width of a first end of the second panel of material, wherein when the textile construction is exposed to moisture, the overlay film structure undergoes an increase in dimension in at least a z-direction to cause the second panel of material to shift in a lengthwise direction which at least partially aligns the second aperture with the first aperture to transition the textile construction to an open state.
