Fjallraven Skule Backpack
Moderate PFAS concern due to water-repellent coating treatment with no public disclosure; seek lower-risk alternatives if PFAS-free verification is important.
The Skule uses G-1000 HD fabric, a durable polyester-cotton blend with a water-repellent coating water-repellent finish. Fjällräven does not publicly disclose whether this treatment contains PFAS or offer any commitment to PFAS-free manufacturing.

What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
PFAS
G-1000 HD includes a water-repellent treatment of undisclosed composition. Modern water-repellent coating can use short-chain fluorocarbons, silicone, or fluorine-free polymers; without brand confirmation, risk level cannot be pinned. Leaching into skin or water is minimal under normal wear but increases with frequent washing or sweat exposure on prolonged trips.
Source: ATSDR ↗Formaldehyde / VOCs
Cotton-polyester blends may use small amounts of formaldehyde-based durable-press or flame-resist resins during manufacture. Off-gassing is typically minimal in finished outdoor gear and dissipates within days of opening. Washing before heavy use reduces exposure further.
Source: ATSDR ↗Microplastic shedding from synthetic fibers
The polyester component will shed microfibers during washing and wear, though the G-1000 construction (thicker and waxed) sheds less than lightweight nylon. This is a material-class issue rather than a brand-specific flaw; washing in a microfiber filter bag reduces environmental release.
What’s reassuring
Azo dyes in polyester component
Polyester-cotton blends can theoretically include azo dyes (which may release banned amines), but Fjällräven's outdoor reputation and lack of reported issues suggest standard, compliant dye batches. No recalls or test failures for this product on record.
Metal hardware (zippers, buckles) composition
Fjällräven typically uses zinc-alloy or stainless steel hardware that meets European safety standards. No lead, cadmium, or nickel leaching issues have been reported for this model.
The full breakdown
What it's made of and why it matters
The Skule uses G-1000 HD, a waxed polyester-cotton blend proprietary to Fjällräven, treated with a water-repellent coating (water-repellent coating) finish. The cotton-polyester base itself poses no known leaching or toxicity concerns under normal use. The water-repellent coating treatment is the material question: traditional formulations used PFOA-based compounds, but many brands have since switched to fluorine-free or short-chain alternatives. Fjällräven has not publicly disclosed which water-repellent coating chemistry they use, creating uncertainty rather than confirmed risk.
The brand's record and disclosure
Fjällräven is a Swedish outdoor brand with a general reputation for durability and sustainability messaging, but they have not published detailed chemical disclosure statements or third-party certifications (such as OEKO-TEX or bluesign) for the Skule line. No recalls or safety controversies specific to this backpack have been recorded. The brand's silence on water-repellent coating chemistry is typical of mid-market outdoor manufacturers but represents a transparency gap compared to leaders in the space.
How it compares in its category
Most mid-range outdoor backpacks use treated nylon or polyester fabrics with water-repellent coating coatings; the Skule's G-1000 HD is more durable and repairable than many competitors. Budget alternatives often use plastic-only construction (higher microplastic shedding risk), while premium competitors (e.g., Patagonia) typically disclose water-repellent coating type and pursue lower-fluorine options. The Skule sits in the middle ground: proven longevity and repairability offset by moderate transparency gaps.
If you buy it
Wash infrequently in cold water with mild soap to preserve the water-repellent coating and minimize any leaching of treatment chemicals. Avoid machine drying and direct heat. The fabric is designed to age and can be re-waxed by the manufacturer if water-repellency declines, extending its life. If PFAS exposure is a personal priority, contact Fjällräven directly to ask about their water-repellent coating supplier and consider a fluorine-free alternative (e.g., Hyperlite, some REI Co-op packs).
