What Is the Role of Elastane Percentage in Sports Bra Support?

Elastane contributes extension and recovery, but sports bra support also depends on structural engineering.

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. Evaluate the full bra rather than composition alone.
