High Exposure Risk — Why This Product Category Matters

Children's underwear is in direct contact with the most sensitive and absorptive areas of the body for 16+ hours daily. Conventional children's underwear often contains PFAS moisture-wicking treatments, synthetic dyes, formaldehyde anti-wrinkle finishes, and synthetic elastic (spandex/Lycra). Children's skin is more permeable than adult skin, and their developing bodies are more vulnerable to endocrine-disrupting chemicals.

Why We Recommend This Product

Primary's GOTS-certified organic cotton underwear is a solid choice for children's intimate apparel. Their focus on simple, safe basics without synthetic treatments makes them a trustworthy option.
