What Decathlon Forclaz Forclaz Trek 100 23?F is made of, ingredients and materials
This jacket uses natural down fill (insulation) paired with a polyester shell fabric. The shell has a water-repellent coating (water-repellent coating) coating, but Decathlon has not disclosed the chemistry. water-repellent coating finishes historically relied on long-chain PFAS (PFAS "forever chemicals") to achieve water resistance; many brands have begun switching to PFAS-free alternatives, but without explicit disclosure from Decathlon, the coating composition cannot be verified.
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.
water-repellent coating (water-repellent coating) coating composition
Polyester shell has an unspecified water-repellent coating that may contain long-chain PFAS or newer alternatives; Decathlon does not disclose the chemistry, making assessment impossible based on available information.
Polyester shell degradation and microfiber shedding
Repeated washing and abrasion of polyester outer fabric can release microfiber particles; this is a concern with all synthetic shells, not specific to Decathlon, and intensifies with high heat drying.
What’s reassuring
Formaldehyde / VOCs
No specific reports of formaldehyde-based finishing resins in this jacket model or Decathlon polyester apparel; polyester itself does not require such treatment, but finishing processes are not disclosed.
Source, ATSDR ↗Azo dyes in polyester shell
No documented cases of hazardous azo dye use in Decathlon polyester shells or recalls related to restricted amines; standard apparel testing does not flag this brand.
Down fill contamination or off-gassing
No recalls or chemical hazards documented for Decathlon down fill; natural down may have minor dust/protein allergen potential in sensitive individuals, but this is inherent to the material, not brand-specific.
The full breakdown
The brand's record and disclosure
Decathlon has not published transparent information about water-repellent coating chemistry in its apparel products or adopted a public PFAS-free commitment for outdoor gear. The brand does not appear on lists of companies with verified PFAS elimination programs. No major safety recalls or chemical controversies specific to this model have been documented in public records, but the absence of disclosure is a red flag for a performance outdoor product.
How it compares in its category
Backpacking insulated jackets typically use either down or synthetic fills; down is lighter and more compressible, making it popular in this category. Many competitors (Patagonia, Arc'teryx, The North Face) now disclose water-repellent coating chemistry or offer PFAS-free certified options. Decathlon's price point is competitive, but transparency lags behind premium brands in the same market segment.
If you buy it
Wash in cool water with down-specific soap to preserve insulation and extend water-repellent coating performance. Avoid high heat (tumble dry on low, no direct heat sources) to prevent polyester degradation and potential release of coating particles. water-repellent coating performance degrades over time and with washing; reapplication products exist but their composition varies. If PFAS exposure is a concern, contact Decathlon directly to request water-repellent coating specification before purchase, and consider brands with published PFAS-free certifications.
