O'Neill · Wetsuits
O'Neill Hyperfreak Fire 4/3 Chest Zip Wetsuit
High PFAS risk typical of sealed wetsuits; no public commitment from O'Neill to PFAS-free water-repellent coating.
Wetsuits require water-repellent durability, and O'Neill does not publicly disclose water-repellent coating chemistry or PFAS status for this model. Sealed neoprene apparel historically relied on fluorinated water-repellents.

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.
