How Does Nylon-Spandex Fabric Compare With Polyester-Spandex for Leggings?

Nylon-spandex and polyester-spandex differ in feel and behavior, but construction strongly influences results.

Fiber percentages alone do not determine performance. Yarn choice, knit structure, finishing, weight, and construction also influence the result; compare actual fabrics using the same test conditions rather than assuming one composition automatically delivers superior comfort, durability, or support. Compare equivalent samples against the same leggings requirements.
