Giant Proshield Rain Jacket
Waterproof jacket with unspecified water-repellent coating; PFAS risk unclear.
Giant does not disclose PFAS content or water-repellent coating chemistry. Rain jackets typically use PFAS-based water repellents, but Giant's specific treatment is unknown. No third-party testing available.

What Giant Proshield Rain Jacket is made of, ingredients and materials
This jacket is polyester, a petroleum-derived synthetic that does not itself leach harmful chemicals under normal wear. The critical unknown is the water-repellent coating (water-repellent coating) coating applied to the fabric. Many water-repellent coating finishes historically used PFOA or other long-chain PFAS "forever chemicals", though modern formulations increasingly use shorter-chain alternatives or fluorine-free options. Giant has not disclosed which type this jacket uses, making the specific chemical profile unclear.
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
The specific water-repellent coating formulation is not disclosed. Older PFC-based coatings persist in the environment; even newer fluorine-free alternatives may contain untested compounds. No test data for this model is publicly available.
Source, ATSDR ↗Microplastic shedding with wear
All polyester garments shed microfibers during washing. The water-repellent coating may slightly reduce shedding by bonding fibers, but synthetic rain jackets are a known microplastic source. Washing in a filtration bag reduces environmental release.
What’s reassuring
Azo dyes in polyester
No specific concerns for Giant Proshield have been reported. Standard polyester apparel dyeing can involve azo dyes, but regulated suppliers avoid the most toxic variants. No recalls or safety warnings exist for this brand's color treatments.
Antimony in polyester fiber
Antimony is occasionally used as a catalyst in polyester production and can leach in trace amounts. Studies show levels are typically far below health concern thresholds in finished garments; no specific data or incidents for Giant exist.
Formaldehyde / VOCs
Some water-repellent treatments have historically included formaldehyde-releasing binders. Modern water-repellent coating coatings often avoid this, but Giant does not specify. No recalls or complaints specific to this model suggest this is not a current focus of concern.

The brand's record and disclosure
Giant (the bicycle and sportswear company) maintains a public sustainability policy but does not prominently disclose water-repellent coating chemistry or restrict PFAS in apparel. The brand has not faced major recalls or public controversies regarding textile safety. However, silence on water-repellent coating composition is common across the outdoor apparel industry and reflects an information gap rather than deliberate concealment.
How it compares in its category
Most budget to mid-range rain jackets use similar polyester-plus-water-repellent coating construction; premium brands often disclose their coating chemistry (some use PFC-free alternatives). Giant sits in the mainstream segment where transparency is limited. Wool or newer synthetic blends with documented fluorine-free treatments offer clearer safety profiles if PFAS concerns are a priority.
If you buy it
Wash separately in cool water and avoid high-heat drying, which can degrade both polyester and water-repellent coating finishes. Dry cleaning is not necessary and may damage the coating. Expect water-repellent coating effectiveness to decline after 50-100 washes; reproof products exist but introduce additional chemical exposure. Inspect seams and zippers annually for wear; replace the jacket once waterproofing fails consistently, as re-coating is costly.
