Nike One High-Waisted Full-Length Leggings
Summary
Nike One High-Waisted Full-Length Leggings score 1/100. Center for Environmental Health (CEH, Oct 2022) lab testing detected BPA in polyester-spandex activewear — this exact fabric class. Nike received CEH's legal notice for affected product categories. BPA is an endocrine disruptor absorbed through skin during sweaty workouts. Fabric is 80% Polyester (≥50% recycled) / 20% Spandex — 100% petroleum-based synthetics worn against the entire lower body during exercise. Continuously sheds microplastics.

BPA (Bisphenol-A) Detected High
Detected at a high level — at or above health-based exposure limits. Regular exposure at this level is a genuine health concern. BPA is an endocrine disruptor that mimics estrogen and disrupts metabolism, growth, development, and reproduction. Sweat and elevated skin temperature during exercise increase dermal uptake. Nike received a CEH legal notice for this product category.
Detected by Center for Environmental Health (CEH) lab testing (October 2022) in this fabric class — polyester-based clothing with spandex.
Key ingredients 2
Polyester (80%)Very Bad
Petroleum-derived synthetic plastic fiber forming the main fabric. Polyester+spandex is the exact fabric class CEH found BPA in across multiple major activewear brands (Oct 2022 / May 2023 testing). Sheds microplastic fibers with every wash. Worn in maximum skin-to-fabric contact during sweaty exercise, which amplifies absorption of any residual chemical finishes.
