This polyester tent includes waterproof coating, but Jack Wolfskin refuses to disclose whether PFAS is involved. Most outdoor fabric waterproofing historically used PFOA or PFOS.

What Jack Wolfskin Sky Dome II Tent is made of, ingredients and materials
The Sky Dome II uses polyester fabric (likely 210D or 300D denier nylon/polyester blend based on typical Jack Wolfskin specs) treated with a water-repellent coating (water-repellent coating) coating and a separate waterproof backing layer. Modern tent water-repellent coating finishes are frequently fluorocarbon-based (PFAS family), though some brands have moved to fluorine-free alternatives. Polyester itself is chemically stable and does not leach additives under normal camping conditions, but the coating chemistry is the primary safety variable here.
What’s concerning
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Waterproof polyester tent textiles commonly use fluorocarbon-based water-repellent coating treatments (PFAS family). Jack Wolfskin has not disclosed the specific chemistry of the Sky Dome II's coating; PFAS presence is unknown but typical of this product class. (Assessed separately from this report per brief.)
Source, ATSDR ↗Microplastics
Polyester fabric and water-repellent coating coatings can flake or degrade with age, friction, or UV exposure, potentially shedding microplastic particles. Tent interiors are not in direct skin contact, minimizing inhalation risk, but degraded coatings reduce waterproofing and may release fine particles into the tent interior air.
Source, EPA ↗Mildew and bacterial growth
Polyester is moisture-resistant but not immune to mildew if stored wet or in humid conditions. Prolonged mildew exposure indoors can trigger respiratory irritation; the fabric itself is not biohazardous, but poor maintenance creates conditions for microbial colonies.
Volatile organic compounds (VOCs) from adhesives and treatments
Factory-fresh polyester tents sometimes off-gas VOCs from dyes, adhesives used in seam sealing, and coating solvents. Off-gassing is typically strongest in the first 24-72 hours and diminishes rapidly with airing; ventilating the tent outdoors before first use reduces exposure.
What’s reassuring
Formaldehyde / VOCs
No recalls or reports link Jack Wolfskin polyester tents to excess formaldehyde. Modern polyester dyeing processes are not heavy users of formaldehyde-releasing chemistry, but pre-purchase airing is still standard practice for any new synthetic textile product.

The brand's record and disclosure
Jack Wolfskin has not published detailed transparency reports on PFAS use in their textile coatings as of available public records. The brand does not advertise PFAS-free or fluorine-free water-repellent coating treatments for the Sky Dome II line. No major safety recalls or contamination incidents are documented for this specific tent model. Direct inquiry to Jack Wolfskin customer service about their water-repellent coating formulation and PFAS content is the only way to obtain specifics.
How it compares in its category
Most mainstream camping tent brands (Big Agnes, REI Co-op, Coleman) similarly do not disclose PFAS status for water-repellent coating coatings; this is industry standard opacity rather than a Jack Wolfskin outlier. A small number of brands (e.g., Hyperlite Mountain Gear, some premium lines) explicitly market PFAS-free or fluorine-free options, but at higher price points. The Sky Dome II is mid-market and offers good durability and weather performance typical of polyester tents in its class, with no documented safety edge over competitors.
If you buy it
Store the tent dry and well-ventilated to prevent mildew; do not store in direct sunlight for extended periods, as UV can degrade the polyester and coating over time. Clean with cool water and mild soap only; avoid harsh chemicals or high-heat drying, which can compromise the waterproof layer. Inspect the seams and coating annually for peeling, cracking, or loss of water beading; re-seal seams if stitching becomes visible. If PFAS exposure is a priority concern, contact the brand for coating composition before committing to purchase.
