What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Formaldehyde / VOCs
Cotton twill in commercial apparel often receives formaldehyde-based wrinkle-resist or anti-shrink finishes. No specific certification or test report for this Banana Republic product is public; residues typically wash out but initial off-gassing in sealed packaging is common.
Source: ATSDR ↗Heavy metals
Indigo and other dyes used in twill may include azo compounds (some restricted in EU but not fully banned in US). Heavy metals such as chromium or copper can be present in dye baths. No hazard warnings or test results for this specific product are available.
Source: FDA ↗Allergens from fragrance or finish residue
Factory-applied finishes or storage treatments may leave traces of fragrance or preservative contact sensitizers. Not labeled as fragrance-free; individuals with dermatitis should wash before wearing.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Antimony in thread or buttons
Since the blazer is stated as 100% cotton, thread is likely cotton or cotton-blend rather than pure polyester. Antimony contamination risk is very low unless buttons contain polyester backing, which is not detailed here.
Microplastics
100% cotton does not shed microplastics during wear or washing, unlike polyester blends. This material class presents no microplastic shedding risk.

What it's made of and why it matters
This blazer is 100% cotton twill, a diagonal-weave fabric made from cellulose fiber. Cotton twill is inherently lower-risk than synthetic blends because it lacks polyester (which may contain antimony) and does not require fluorinated water repellents (PFAS source). Plain cotton dyes and finishes in basic business wear typically involve lower chemical loads than performance textiles, though formaldehyde-based finishing resins are still possible in the supply chain.
The brand's record and disclosure
Banana Republic (Gap Inc.) has not published detailed chemical disclosures or ZDHC Gateway data for individual garments as of recent public records. The brand maintains general sustainability commitments but does not routinely disclose formaldehyde-free or azo-dye-free certification for this product line. No major safety recalls or chemical contamination scandals specific to cotton twill blazers from this brand are on record.
How it compares in its category
Plain cotton twill blazers occupy the safer middle ground of apparel. They avoid synthetic fiber antimony and halogenated flame retardants found in polyester blends or tech fabrics. However, they offer no advantage over certified organic or GOTS-labeled competitors in formaldehyde or dye management. Banana Republic's mid-market positioning means less transparency than luxury brands (which often test for heavy metals) but also less aggressive stain-resist or wrinkle-free chemistry than budget fast-fashion.
If you buy it
Wash in cool water before wearing to rinse out excess dyes and potential formaldehyde residue. Avoid high heat drying, which can set any residual finishing chemicals. Inspect seams and buttons for loose threads or plating wear over time. Store in a breathable garment bag to prevent mildew; cotton does not off-gas like synthetics but can absorb odors and moisture.
