Is it safe for babies to wear PFAS-coated swim diapers?
Based on 2 peer-reviewed studiesbaby
Verdict: Avoid
No. Warm pool water and sweat pull PFAS from swim diapers through sensitive skin.
What's actually in it
Many reusable swim diapers use PFAS-coated synthetic fabric to repel water and hold solids. Pool water, warmth, and baby skin are all conditions that speed chemical transfer.
What the research says
A 2025 study in Sci Total Environ showed sweat pulled PFAS from kids' textiles through a skin model. A 2025 study linked PFAS in household dust to childhood leukemia.
Look for swim diapers labeled "PFAS-free". Some brands use natural rubber or a waterproof organic cotton layer instead. Disposable swim diapers are PFAS-free for the most part.
