Jack Wolfskin Mens Activate XT
Skip until brand discloses water-repellent coating chemistry, silent on PFAS in weatherproof apparel is a red flag.
The Activate XT is an outdoor jacket with water-repellent treatment, a category historically reliant on PFAS-based water-repellent coating coatings. Jack Wolfskin makes no public disclosure about PFAS avoidance or alternative chemistry.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
