Carhartt Men's Storm Defender Jacket
Waterproof jacket with unknown water-repellent coating chemistry; Carhartt silent on PFAS.
Storm Defender uses water-repellent coating but Carhartt does not disclose PFAS status or alternatives. High uncertainty without lab testing or brand transparency.

The full breakdown
What it's made of and why it matters
This jacket uses nylon and polyester blended shell with a water-repellent coating (water-repellent coating) treatment applied to the outer surface. water-repellent coating coatings shed water without creating a waterproof membrane, relying on surface tension rather than barrier films. The specific water-repellent coating chemistry is not disclosed by Carhartt; traditional water-repellent coating finishes are fluorocarbon-based (PFAS-containing), though some manufacturers now use non-fluorinated alternatives. Nylon and polyester themselves are chemically stable and pose no inherent hazard during wear, but degradation or washing can affect the coating.
The brand's record and disclosure
Carhartt does not publicly disclose water-repellent coating chemistry or commit to PFAS-free formulations on product pages or corporate sustainability reports reviewed to date. The company has no widely documented PFAS phase-out announcement comparable to brands like Patagonia or The North Face. Carhartt is primarily known for durability and workwear performance rather than chemical transparency. Without direct communication, water-repellent coating treatment source and fluorination status cannot be confirmed.
How it compares in its category
Most mainstream workwear jackets use fluorinated water-repellent coating treatments; Carhartt's lack of disclosure places it in the majority of conventional manufacturers. Premium outdoor brands (e.g., Patagonia, Arc'teryx) explicitly market non-fluorinated or PFAS-free water-repellent coating options at comparable or higher price points. Budget workwear alternatives often use the same water-repellent coating chemistry without labeling. If PFAS exposure is a concern, requesting documentation or choosing brands with published PFAS-free claims offers more certainty.
If you buy it
Wash separately at low temperature before first wear to remove loose finishes or residues. Do not dry-clean; high heat or solvents can degrade the water-repellent coating. Avoid prolonged contact with skin oils or sunscreen, which can reduce water repellency. water-repellent coating effectiveness degrades with repeated washing; reapply aftermarket water-repellent coating spray yearly if continued water resistance is needed. Do not incinerate at end of life.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Azo dyes in polyester
Carhartt's polyester is not documented to use restricted azo dyes. Standard disperse dyes in polyester are legal and non-mutagenic under standard conditions; no recalls or reports of concern for this brand's workwear line are on record.
Formaldehyde in textile resins
Nylon and polyester fabric may contain residual formaldehyde from dyes or finishing resins applied during manufacture. Levels in finished workwear are typically below regulatory limits; off-gassing is minimal after one wash. Carhartt does not guarantee formaldehyde-free production.
Antimony in polyester fiber
Polyester fiber itself does not contain antimony. If a polyester-specific catalyst residue were present, it would be bound in the polymer and not released during normal wear or washing.
water-repellent coating leaching or inhalation
If the water-repellent coating treatment is fluorinated, small amounts may leach into wash water or release as particulates during wear. Inhalation risk is negligible during normal use. Primary concern is environmental persistence and bioaccumulation after garment disposal or repeated washing.
Fragrance or optical brighteners
Carhartt workwear is not marketed with added fragrance. Optical brighteners (if used) are industry-standard and not hazardous at typical application rates. No documented allergenic complaints specific to this product line are on record.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
