Ingredient

Elastane (9%)

Flagged in 2

Scout's take

Petroleum-derived polyurethane at 9% — nearly double what health-conscious brands like NADS use (5%). No BPA-free claim. A 2025 study found underwear elastane contained BPA, BPS, and BPF at concentrations up to 52,967 ng/g with high sweat migration rates. No genital liner to isolate the most absorptive skin from this synthetic.
