Abstract
A fluid-filled chamber may have a barrier, a stacked tensile member, and a fluid. The barrier may be formed from a polymer material that is sealed to define an interior void. The stacked tensile member may be located within the interior void and includes a first tensile element and a second tensile element that are joined to each other. Additionally, opposite sides of the stacked tensile member are joined to the barrier. The fluid is located within the interior void and may be pressurized to place an outward force upon the barrier and induce tension in the stacked tensile member. In some configurations, each of the tensile elements may be a spacer textile.
