Abstract: Tights, leggings, training pants, spots pants, and other types of pants include multiple pants-regions. A first pants-region covers a first body-part; and a second, non-adjacent, pants-region covers a second body-part. A decoupling pants-region is connected in between the first pants-region and the second pants-region. The decoupling pants-region expands or shrinks or otherwise modifies its size or dimensions or properties, in order to decouple between movement of the first pants-region and movement of the second pants-region, in response to a human wearer movement of one or more body parts.
