Sierra Designs Full Moon 2 Tent
Skip until Sierra discloses water-repellent coating chemistry, traditional tent coatings often contain PFAS.
The Sierra Designs Full Moon 2 is a backpacking tent with a polyester shell treated with a water-repellent finish, a category historically reliant on PFAS-based water-repellent coating coatings. Sierra does not publicly disclose the composition of their water-repellent coating treatment or make a PFAS-free claim.

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.
