The only clothing your child wears
shouldn't come with hidden chemicals.
PFAS — "forever chemicals" — are found in thousands of children's clothing items. PureThread Kids curates brands that are rigorously tested and certified free.
Why PFAS-free clothing matters
PFAS (per- and polyfluoroalkyl substances) are a group of over 12,000 synthetic chemicals used to make fabrics water-resistant, stain-resistant, and wrinkle-free. They don't break down — in the environment or in your child's body.
Linked to health risks
Studies connect PFAS exposure in children to hormone disruption, immune suppression, and developmental delays. Children absorb more through skin contact than adults.
Hidden in clothing
PFAS are used in water-repellent coatings, stain guards, and flame retardants — often without disclosure on the label. You can't see or smell them.
"Forever" chemicals
PFAS accumulate in soil, water, and human tissue and never fully degrade. Choosing PFAS-free clothing reduces your family's total chemical burden over a lifetime.

What do the certifications mean?
Third-party certifications are the best tool parents have for verifying claims. Here's what each mark actually guarantees.
Global Organic Textile Standard
Restricts PFAS and hundreds of harmful substances across the full supply chain — from raw fiber to finished garment. The gold standard for organic textiles.
Highest ProtectionSTANDARD 100 by OEKO-TEX
Tests every component of the finished garment for harmful substances including PFAS, heavy metals, pesticides, and formaldehyde. Widely trusted and audited annually.
High Protectionbluesign® Approved
Focuses on the manufacturing process — bans PFAS in production chemistry and dyeing. Common in performance and outdoor wear where water-resistance treatments are typical.
Strong ProtectionFair Trade Certified
Primarily covers ethical labor, but also restricts many chemical inputs used in textile production, including PFAS-based finishes. Best used alongside GOTS or OEKO-TEX.
Partial CoverageFrequently asked questions about PFAS in kids' clothing
Everything parents need to know before buying children's clothing — answered plainly.
What are PFAS chemicals in clothing?
PFAS (per- and polyfluoroalkyl substances) are a group of over 12,000 synthetic chemicals used to make fabrics water-resistant, stain-resistant, and wrinkle-free. They are called "forever chemicals" because they don't break down — in the environment or in the human body. They're found in outerwear, school uniforms, rain gear, and some everyday basics.
Is PFAS in children's clothing dangerous?
Yes. Studies link PFAS exposure in children to hormone disruption, immune suppression, and developmental delays. Children are particularly vulnerable because they absorb more chemicals through skin contact than adults, and their developing systems are more sensitive to endocrine-disrupting substances. Infants and toddlers — who put clothing in their mouths — face the highest exposure risk.
How can I tell if kids' clothing is PFAS-free?
Look for third-party certifications: GOTS, OEKO-TEX STANDARD 100, or bluesign. These independent organizations test for PFAS and hundreds of other harmful substances. Marketing terms like "natural," "eco-friendly," or "green" are not verified claims — they do not guarantee PFAS-free manufacturing.
Are all organic kids' clothes PFAS-free?
Not necessarily. "Organic" on a label typically refers to how the fiber was grown, not how the finished garment was treated. A garment made from organic cotton can still receive a PFAS-based water-repellent or stain-resistant finish after weaving. Always look for GOTS or OEKO-TEX certification, which covers the entire production process — not just the raw material.
What clothing types are most likely to contain PFAS?
Outerwear and rain gear carry the highest risk — waterproof coatings commonly use PFAS-based DWR (durable water repellent) treatments. Also watch out for stain-resistant school uniforms, sports uniforms, and some sleepwear treated with flame retardants. When in doubt, check for a certification before buying.
