Giant Proshield Anorak Rain Jacket
Skip until Giant discloses water-repellent coating chemistry or certifies PFAS-free.
Giant's Proshield Anorak uses a water-repellent coating, a common PFAS application, but Giant provides no public disclosure of coating chemistry or PFAS status. Without third-party verification or explicit PFAS-free claims, risk profile remains unclear.

What Giant Proshield Anorak Rain Jacket is made of, ingredients and materials
This jacket is polyester with a water-repellent coating (water-repellent coating) coating applied to the fabric surface. water-repellent coating coatings are the primary PFAS delivery mechanism in rain gear; they create a water-shedding layer but historically relied on fluorochemicals that persist in the environment and accumulate in human blood. The polyester base itself is inert, but the coating's chemistry is the critical unknown here.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.

No PFAS disclosure
No public statement from the brand about PFAS in this product.
PFAS
Standard fluorochemical water-repellent coating coatings (legacy Teflon-type coating-based or PFOA analogs) are the default in mid-market rain gear; Giant's silence on this product suggests no reformulation. PFAS bioaccumulates and is linked to immune, thyroid, and developmental effects in medical literature.
Source, ATSDR ↗Azo dyes
Polyester textiles may be dyed with azo dyes; some can cleave under stress or sweat to form carcinogenic amines. Giant has not published dye standards or OEKO-TEX certification for this jacket, leaving risk unknown.
Formaldehyde / VOCs
Wrinkle-resistance or stiffening finishes on polyester can release low levels of formaldehyde, especially in new garments. Proper laundering before wearing and airing reduces this; no specific data on Giant Proshield finish chemistry is available.
Source, ATSDR ↗Microfiber shedding during wash
All polyester garments shed microfibers in the wash; coated rain jackets may shed additional particles from the water-repellent coating layer. These fibers persist in aquatic ecosystems and can carry adsorbed PFAS; minimizing wash frequency and using mesh wash bags reduces environmental load.
What’s reassuring
Antimony in polyester
Antimony is sometimes used as a catalyst in polyester production but is typically bound in the polymer matrix and poses minimal risk during normal wear. No specific testing or concerns documented for Giant Proshield in this regard.
The full breakdown
The brand's record and disclosure
Giant is primarily a bicycle manufacturer and has not published transparency reports or certifications regarding PFAS use in apparel products. The brand has remained silent on water-repellent coating chemistry in rain jackets despite growing industry pressure to disclose or eliminate PFAS. No public commitment to PFAS phase-out or third-party verification (e.g., Cradle to Cradle, OEKO-TEX) has been announced for this product line.
How it compares in its category
Many mainstream rain jacket brands now offer PFAS-free water-repellent coating alternatives using wax-based or polyurethane coatings, though durability typically declines faster. Patagonia, The North Face, and others have committed to phasing out legacy PFAS in water-repellent coating. Giant's lack of transparency positions this jacket behind competitors who explicitly certify PFAS-free or disclose their chemistry.
If you buy it
Launder separately in cool water to minimize microfiber and any coating particle shedding into shared waterways. Avoid high heat (tumble dry on low or air dry only) to prevent coating degradation and potential fume release. Replace the jacket when water-repellent coating performance visibly declines (water beads poorly) rather than re-treating it, since reapplication chemistry is unknown. Do not donate or discard without checking local textile recycling; standard trash and landfill pathways expose PFAS to groundwater.
