Men Giant Diversion Jacket
Typical outdoor jacket; water-repellent coating likely contains PFAS. Brand discloses nothing.
Giant's Diversion Jacket is a standard synthetic jacket with water-repellent finish typical of outdoor wear. No PFAS disclosure or certification available; water-repellent coating treatments commonly use PFAS compounds.

What Men Giant Diversion Jacket is made of, ingredients and materials
The Giant Diversion Jacket uses polyester and nylon as the primary shell fabrics, which are synthetic polymers with good durability and moisture management. The water-repellent (water-repellent coating) coating applied to the exterior is the chemical concern, outdoor jackets in this class typically use fluorinated water-repellent coating finishes that contain PFAS compounds to achieve water beading and breathability. The polyester/nylon fibers themselves are chemically stable during normal wear, but the surface treatment is where persistent chemical exposure originates.
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 finishes on outdoor jackets in this price/category typically use fluorinated compounds. Coating degradation with washing and wear may release PFAS into water and soil. (Covered separately in PFAS assessment.)
Source, ATSDR ↗Antimony in polyester
Polyester production may use antimony trioxide as a catalyst; trace residues can remain in finished fabric. At typical wear exposure levels, this poses minimal skin contact risk, but the hazard is inherent to polyester chemistry and cannot be ruled out without material certification.
Formaldehyde / VOCs
Water-repellent and wrinkle-resist finishes sometimes incorporate formaldehyde-releasing compounds. Giant provides no disclosure. If present, off-gassing is highest in the first few washes; airing the jacket outdoors before first wear reduces exposure.
Source, ATSDR ↗Microplastic shedding during wear and washing
All synthetic polyester/nylon textiles shed microfibers. Washing synthetic jackets releases thousands of fibers per cycle; this is an environmental concern rather than direct consumer health risk, but relevant to material class impact.
What’s reassuring
Azo dyes and synthetic colorants
No specific recalls or warnings exist for Giant Diversion Jacket dyes. Polyester can be dyed with azo compounds, but reputable brands typically comply with EU/US azo dye restrictions. No public evidence contradicts Giant's compliance here.
The full breakdown
The brand's record and disclosure
Giant (the bicycle and outdoor apparel manufacturer) does not publicly disclose the specific chemistry of its water-repellent treatments or commit to PFAS-free water-repellent coating alternatives on its product labels or website. No third-party certifications (such as Bluesign or OEKO-TEX) are listed for this jacket model. This silence is consistent with most mainstream outdoor apparel brands, which have been slow to adopt fluorine-free water-repellent coating despite growing availability of such coatings since the late 2010s.
How it compares in its category
This jacket sits in the typical mid-market outdoor apparel range where PFAS-containing water-repellent coating coatings remain standard practice. Brands like Patagonia and Arc'teryx have begun transitioning to PFAS-free water repellency, but Giant has not announced such a shift. The polyester/nylon material combination is industry standard and poses no chemical risk beyond the water-repellent coating; the real differentiation in this category is whether manufacturers disclose or eliminate PFAS.
If you buy it
Wash the jacket sparingly in cold water and air dry to minimize water-repellent coating degradation and shedding of microfibers. Avoid tumble drying, which generates heat that can accelerate polymer breakdown and increase microparticle release. Do not use fabric softeners or bleach. Replace when the water-repellent properties visibly fail (water no longer beads on the surface), as reapplication of consumer water-repellent coating products often contains additional PFAS or other chemicals.
