Jason Markk Repel Refill Shoe & Hat Protectant
Skip until brand discloses coating chemistry or tests.
Jason Markk's repel spray provides durable waterproofing but uses undisclosed proprietary coating. No PFAS claims or third-party testing available; higher caution warranted for water-resistant treatments.

The full breakdown
What it's made of and why it matters
Jason Markk Repel is a proprietary spray-applied water and stain repellent for textiles and footwear. The exact chemical composition is not publicly disclosed, which is standard practice for branded coating products but limits independent safety assessment. Spray application means inhalation exposure is the primary route of concern during use. The product is designed to bond to fabric fibers rather than remain on the surface, suggesting a coating chemistry that cross-links or polymerizes on the substrate.
The brand's record and disclosure
Jason Markk is a premium footwear care brand with no documented recalls or safety complaints in public records. The company does not publicly disclose whether its water-repellent formulation contains PFAS (per fluorinated compounds), does not claim PFOA or PFOS-free status, and provides no third-party testing certificates for VOC or hazardous chemical content. This silent stance on chemistry is a significant transparency gap, especially given industry-wide scrutiny of PFAS in water repellents. No certifications such as Bluesign, OEKO-TEX, or GOTS are advertised.
How it compares in its category
Most spray fabric protectants in the footwear market either use PFAS-based chemistries (cheaper, more durable) or newer paraffin/silicone/fluorocarbon alternatives marketed as PFAS-free. Jason Markk does not declare which approach it uses, placing it in a middle ground of uncertainty. Competitors such as Crep Protect and Sneaker Lab also do not disclose PFAS status, but some brands (e.g., those certified Bluesign) are more transparent. For users seeking proven PFAS-free options, this product does not provide the assurance needed.
If you buy it
Apply in a well-ventilated space or outdoors to minimize inhalation of spray mist and propellant vapors. Do not inhale fumes and allow sprayed items to dry fully (typically 24 hours) in open air before wearing or storing in enclosed spaces. Reapply every 6-12 months depending on wear and washing frequency; reapplication frequency is higher than solvent-based alternatives. Store the bottle in a cool, dry place away from heat and direct sunlight, and follow the label instructions for distance and number of coats to avoid over-saturation.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Volatile organic compounds (VOCs) and inhalation risk
Spray-applied protectants inherently release propellant and solvent vapors during application. Jason Markk does not disclose VOC content or air quality testing. Inhalation exposure during application is significant and controllable only through ventilation practices.
Formaldehyde or formaldehyde-releasing agents
No public records indicate formaldehyde resins in Jason Markk Repel. Fabric protectants typically do not use formaldehyde-based chemistry, but undisclosed proprietary formulas cannot be ruled out without testing.
Azo dyes or toxic colorants in the product itself
The spray itself is clear or nearly colorless and contains no added dyes. No hazard reported or plausible in this product type.
Flame retardants or halogenated compounds
Some water-repellent coatings use brominated or chlorinated compounds as co-stabilizers or durability enhancers. Jason Markk does not disclose ingredient chemistry, so the presence of halogenated additives cannot be confirmed or ruled out.
Skin sensitization from residual coating or fragrance
Direct skin contact with wet spray or fully cured coating is unlikely during normal use, but fragrance is sometimes added to shoe care products. Jason Markk Repel has minimal perceptible odor, suggesting low fragrance content, but no allergen declaration is provided.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
