Critical Exposure Risk — Why This Product Category Matters

Underwear is in direct, prolonged contact with some of the body's most sensitive and absorptive skin. Synthetic fabrics release microplastics and phthalates through dermal absorption. For children, whose skin is thinner and more permeable, this exposure is particularly concerning.

Why We Rated It This Way

Adidas performance underwear has the same fundamental problems as Nike's — high synthetic content, moisture-wicking treatment, and direct skin contact. Not appropriate for daily wear by children.
