What Old Navy Kids' School Pique Polo Shirt is made of, ingredients and materials
This shirt is cotton pique knit, a durable textured weave commonly used in casual and uniform wear. Cotton pique is inherently low-chemical compared to synthetic blends because it requires no Teflon-family coating water-repellent coatings or antimony-based flame retardants typical of polyester. The main chemical exposure pathway in cotton garments is residual dyes and finishing agents applied during manufacturing rather than the fiber itself.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Heavy metals
Cotton textiles rely on synthetic dyes, some of which may contain trace heavy metals (lead, cadmium) if sourced from low-cost suppliers without strict chemical controls. No testing data is available for this specific product, but risk is typical for budget children's clothing.
Source, FDA ↗Formaldehyde / VOCs
Cotton pique is often treated with formaldehyde-releasing resins to improve wrinkle resistance and shape retention. Levels decline sharply with washing; no acute hazard is expected for school-age wear, but high off-gassing risk exists before first wash.
Source, ATSDR ↗Allergenic fragrance or dyes
Some children experience contact dermatitis from synthetic dyes or sizing agents in new cotton garments. Pre-washing mitigates this risk substantially. No specific allergen warnings from Bienzle are documented.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Chlorine bleach sensitivity
No specific vulnerabilities documented for this product. Standard caution applies, avoid household bleach to prevent dye damage and potential chemical interactions with finishes.
Flame retardants
Cotton pique does not require brominated or phosphorus flame retardants by regulation for school uniforms worn on the body. Bienzle has not announced any added flame treatments for this line.

The brand's record and disclosure
Bienzle has no public chemical transparency initiatives or third-party certifications (OEKO-TEX, GOTS, bluesign) on record for this product line. Old Navy, the parent retailer, has basic supplier compliance policies but does not publish detailed chemical testing results for kids' clothing. No significant recalls or safety controversies involving this specific uniform line are documented.
How it compares in its category
Cotton pique uniforms are safer than polyester-blend alternatives, which often contain antimony catalysts and higher flame-retardant chemical loads. However, unbranded or budget cotton uniforms may use cheaper azo dyes with heavy metal contaminants. This product sits in the middle-market range, no premium certifications but also unlikely to contain banned hazardous dyes.
If you buy it
Wash in cool water before first wear to remove residual dyes and finishes. Avoid high-heat drying, which can set any remaining dye chemicals into the fabric. Replace when seams fray or color fades significantly, as worn finishes may release fibers. Cotton pique is machine-washable indefinitely; no special care needed beyond standard laundry.
