Old Navy Kids' School Uniform Polo Shirt 3-Pack
Lower concern. Plain cotton blend with no performance coating disclosed.
School uniform polo in standard cotton blend without water-resistant or stain-guard treatments. Old Navy makes no PFAS claims, and untreated cotton clothing carries lower PFAS risk than coated textiles.

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.
Azo dyes and excess dye residue
Cotton-blend polos use synthetic azo dyes for color fastness. Excess unfixed dyes can migrate in sweat or during washing, particularly in the first few launders. Risk is low if dyes are properly fixed, but no third-party testing of this specific 3-pack is publicly available.
Formaldehyde / VOCs
Polyester-cotton blends may be treated with formaldehyde-releasing resins for wrinkle resistance or stiffness during finish. This product does not claim wrinkle-free treatment, suggesting lower use, but trace exposure during manufacture and wear is typical for this material class and dissipates quickly with laundering.
Source, ATSDR ↗Microfiber shedding from polyester component
The 40% polyester blend will shed microfibers during washing, as with all synthetic apparel. This is an environmental rather than direct health hazard but relevant for household water systems. Use a wash bag or lint filter to reduce shedding.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Antimony as polyester catalyst residue
Polyester typically contains antimony oxide as a catalyst during synthesis. Modern manufacturing removes most residual antimony; no documented contamination in Old Navy apparel is on record, and migration into skin contact is minimal for finished fabric at body temperature.
Fragrance or antimicrobial treatments
This product is marketed as plain school wear with no stated odor control, moisture-wicking, or antimicrobial finish. Unlisted chemical treatments are unlikely, though unscented softeners or dyes may carry fragrance allergens; review final product label for any 'antimicrobial' or 'treated' claims.
The full breakdown
What it's made of and why it matters
Old Navy's kids' polo is a cotton-blend knit (typically 60% cotton, 40% polyester or similar ratio based on standard Old Navy construction). The cotton component reduces risk of synthetic fiber shedding and moisture-trapping versus 100% polyester. No water-repellent or stain-resistant finish is claimed, which eliminates the primary vector for PFAS fluorochemical coatings on apparel. The polyester portion introduces minimal hazard if dyes and finishing chemicals are controlled during manufacture.
The brand's record and disclosure
Old Navy (Gap Inc. subsidiary) does not publicly state PFAS-free commitments for apparel, though parent company Gap Inc. has joined industry commitments on chemical management in some categories. No specific textile certifications (OEKO-TEX, GOTS) are advertised for this 3-pack, which is typical for mass-market basics. No recalls or documented heavy-metal or formaldehyde violations specific to Old Navy kids' polos are on public record.
How it compares in its category
School uniform polos from mass retailers (Old Navy, Target, Walmart) occupy the middle of the safety spectrum. They avoid the treatment intensity of performance/outdoor kids' apparel, but lack third-party chemical certifications common in premium or eco-focused brands. Cotton-blend composition is standard and safer than 100% synthetic alternatives; the lack of stain treatment is a safety advantage relative to marketed 'stay-clean' or 'wrinkle-free' polos.
If you buy it
Wash new shirts 1-2 times before first wear to remove loose dyes and residual finishing chemicals. Use cold water and standard detergent; no special care is required. Inspect seams and printing annually for degradation. Replace if elasticity noticeably declines or dyes separate/crack, which signals coating failure. Standard cotton-blend durability for school wear is 1-2 school years with weekly laundering.
