Carhartt Men's Loose Fit Heavyweight Storm Defender Jacket
Heavy workwear likely treated with water-repellent coating; coating details undisclosed.
Carhartt does not disclose PFAS status for this jacket. water-repellent coating coatings on workwear commonly use PFAS, but specific treatment unknown. Low transparency limits confidence.

What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
PFAS
Carhartt does not disclose whether this jacket uses legacy PFOA/PFOS or newer short-chain PFAS alternatives. Standard heavy-duty workwear water-repellent coating is almost universally PFAS-based; coating degrades and leaches with washing and body heat, creating repeated low-level exposure.
Source: ATSDR ↗Formaldehyde / VOCs
Cotton-poly blends often receive formaldehyde-based resin treatments for wrinkle resistance and shrink control. Carhartt does not certify against formaldehyde in product specs. Levels in finished fabric are typically low but can release with heat and washing.
Source: ATSDR ↗Azo dyes in synthetic colorants
The dark colors typical of Carhartt workwear may use azo dyes, which can release carcinogenic aromatic amines under certain wear or washing conditions. No brand certification for azo-free alternatives is evident.
Coating degradation and microfiber shedding
water-repellent coating coatings on textiles naturally degrade through washing and friction, releasing microplastics and residual PFAS into wash water. Carhartt jackets worn frequently will shed coating fibers, particularly after 50+ wash cycles.
What’s reassuring
Antimony in polyester component
Antimony is sometimes used as a catalyst in polyester production but is not a documented concern in Carhartt apparel. Modern polyester generally does not release measurable antimony after manufacturing.
The full breakdown
What it's made of and why it matters
This jacket is a cotton-polyester blend (typical ratio around 60/40 or 65/35) with a water-repellent coating (water-repellent coating) finish applied to the outer surface. water-repellent coating coatings on workwear are almost always PFAS-based fluorochemicals that bond to fabric fibers to shed water and stains. The blend itself is stable, but the coating is the primary chemical concern because it can degrade, shed microfibers, and leach with repeated washing or body heat.
The brand's record and disclosure
Carhartt has not publicly committed to PFAS-free alternatives or provided transparency on which PFAS chemicals are used in their water-repellent coating treatments. The company does not disclose coating composition on product labels or websites. Other major workwear brands (like Fjallraven and some Arc'teryx lines) have begun phasing to PFAS-free or low-fluorine options, making Carhartt's silence notable for a premium workwear maker in 2024.
How it compares in its category
Carhartt jackets are industry-standard for construction and outdoor labor. Most competing heavy workwear at this price point (Dickies, Walls, Key Apparel) also use PFAS-water-repellent coating coatings without disclosure. Untreated cotton canvas or waxed alternatives exist but sacrifice water-shedding performance and durability. This product sits in the mainstream workwear tier for PFAS exposure risk.
If you buy it
Wash separately from other clothes in cool to warm water (not hot) before first use and periodically to reduce PFAS residue and coating shedding. Avoid high heat from dryers or direct fire; air dry to preserve the water-repellent coating layer and minimize fume release. Replace when coating noticeably loses water-repellency (typically 2-4 years of regular wear) rather than retreating with aftermarket products. Limit wearing directly against bare skin if possible; use a base layer underneath.
