Ghostek Galaxy S25 Waterproof Case Military Grade 10FT Drop Protection — Nautical
Skip until Ghostek discloses waterproofing chemistry, 10ft drop claims often hide PFAS-based water-repellent coating.
Ghostek's military-grade waterproof case uses an undisclosed coating to achieve water resistance. The brand makes no public statement about PFAS or alternative chemistries.

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 38% 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.
