Giant Proshield Mens MTB Jacket
MTB jacket with water-repellent coating, PFAS details undisclosed by Giant.
Giant does not publicly disclose PFAS content or water-repellent coating treatment chemicals for this MTB jacket. Water-repellent outdoor apparel typically uses water-repellent coating coatings that may contain PFAS; confirmation requires direct brand inquiry.

What Giant Proshield Mens MTB Jacket is made of, ingredients and materials
This jacket is polyester with a water-repellent coating (water-repellent coating) finish applied to the surface. Polyester itself is chemically stable during normal wear and washing. The water-repellent coating is the concern, most outdoor apparel water-repellent coating treatments historically used long-chain PFOA or similar forever chemicals, though some brands have switched to shorter-chain or non-fluorinated alternatives. Giant has not publicly disclosed which water-repellent coating chemistry they use in this model.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
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.
PFAS
Water-repellent coating finishes on polyester textiles commonly contain PFAS unless explicitly stated otherwise. Giant provides no public information on their water-repellent coating chemistry, making PFAS presence probable but unconfirmed for this specific jacket.
Source, ATSDR ↗Formaldehyde / VOCs
Polyester fabrics may contain trace formaldehyde from manufacturing resins or anti-wrinkle treatments. Typical levels in finished apparel are low and off-gas minimally during wear, but Giant does not disclose processing chemistry.
Source, ATSDR ↗Degradation and microfiber shedding during washing
Polyester textiles shed microplastics when laundered, particularly if the water-repellent coating degrades. This is an environmental and potential ingestion concern over product lifetime, not an acute safety hazard during wear.
What’s reassuring
Azo dyes
No specific recalls or warnings exist for Giant MTB jackets. Polyester apparel dyes are regulated in most markets; restricted azo dyes are uncommon in retail clothing, though independent testing would be required to rule out completely.
Antimony in polyester fiber
Antimony is used as a catalyst in polyester production. Most antimony remains bound in the polymer; migration into skin contact is negligible under normal wear conditions and is not a documented concern for cycling apparel.
The full breakdown
The brand's record and disclosure
Giant (primarily a bicycle manufacturer) does not publish material transparency reports or PFAS phase-out commitments comparable to major outdoor apparel brands like Patagonia or Arc'teryx. No specific safety recalls or chemical controversies are documented for Giant textiles. Their silence on water-repellent coating composition reflects a broader lack of chemical accountability in the cycling apparel market, where disclosure lags behind mainstream outdoor wear.
How it compares in its category
Most MTB and cycling jackets use polyester with water-repellent coating coatings. Giant's positioning is mid-market; premium brands increasingly disclose non-PFAS or PFAS-free water-repellent coating options, while budget alternatives often do not. Without composition data, this jacket is harder to assess than branded alternatives from companies with public PFAS reduction commitments. The polyester base itself is standard and unremarkable across the category.
If you buy it
Wash in cool water and dry at low heat or air dry to preserve the water-repellent coating finish and avoid any potential thermal off-gassing from coatings. Do not machine dry at high heat. Expect the water-repellent coating water beading to diminish after 20-30 washes; some users re-apply commercial water-repellent coating treatments, which reintroduces the same uncertainty. Before purchase, contact Giant to ask about water-repellent coating chemistry; their response (or lack thereof) may inform your confidence in the product.
