What Klymit Cross Canyon Tent is made of, ingredients and materials
The Klymit Cross Canyon uses polyester fabric, a stable synthetic that resists mildew and UV degradation well in outdoor conditions. The critical unknown is the water-repellent coating (water-repellent coating) finish, most outdoor tents historically used PFOA or PFOS-based treatments, though some brands have migrated to Teflon-type coating or non-fluorinated alternatives. Khyam does not publicly disclose the chemistry of their waterproof coating, making it impossible to assess whether this tent contains legacy or modern PFAS compounds.
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
Polyester camping tents typically receive fluorochemical water repellent treatments; Khyam's refusal to disclose coating chemistry suggests either legacy PFAS formulations or reluctance to engage with the issue. No independent testing of this specific model is publicly available.
Source, ATSDR ↗Coating degradation and leachate
As water-repellent coating coatings age, they can break down and shed microparticles or semisoluble compounds into groundwater or runoff during storage or washing. This risk increases if the coating is PFAS-based and deteriorates in UV light or with repeated compression.
What’s reassuring
Formaldehyde / VOCs
Khyam does not advertise OEKO-TEX or similar certification. Standard polyester tent fabrics carry low formaldehyde risk when used outdoors, but interior coatings or adhesives used in seam sealing could theoretically harbor residues. No recalls or complaints specific to this tent have been documented.
Source, ATSDR ↗VOC off-gassing from adhesives or sealants
New tent tents occasionally release mild odors from seam-sealing adhesives or thermal bonding agents. This product has no documented complaints of excessive off-gassing and is typically ventilated in use, minimizing inhalation risk.
Antimony in polyester yarn
Polyester production may use antimony trioxide as a catalyst, but concentrations in finished fabric are generally below concern levels. Khyam does not provide supplier chain transparency, so antimony levels cannot be verified independently.
How is this PFAS grade calculated?
The brand's record and disclosure
Khyam is a UK-based brand with a long heritage in canvas and modern outdoor gear, but maintains minimal public transparency on chemical safety or material sourcing. No independent certifications (such as BLUESIGN, OEKO-TEX, or Cradle to Cradle) are advertised for this model. The brand has not published statements on PFAS phase-out or disclosed alternatives, and no recalls related to chemical hazards have been documented for this specific tent model.
How it compares in its category
Many mainstream camping tents (including budget options from Coleman and REI Co-op lines) now explicitly market PFOA-free or fluorine-free water-repellent coating coatings in response to consumer pressure. Klymit's silence on this issue puts it behind transparent competitors but does not indicate active use of banned substances. Mid-range tents increasingly carry third-party certification; this product's lack of such marking is a competitive disadvantage, not definitive proof of harm.
If you buy it
Store the tent dry and in shade to prevent mold growth and extend coating life; avoid machine washing or high-heat drying, which can degrade the water-repellent coating finish. Do not use solvents or aggressive scrubbing on the fabric. Inspect seams and coating annually for wear; reapplication of commercial water-repellent coating products (many now marketed as PFAS-free by manufacturers) can extend the tent's usable life. If the coating visibly degrades or water begins pooling on the surface rather than beading, replacement or re-treatment becomes necessary.
