Nanuk 909 Waterproof Hard Case for DJI Osmo Pocket 3
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes polypropylene shell, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What Nanuk 909 Waterproof Hard DJI Osmo Pocket is made of, ingredients and materials
The Nanuk 909 uses a polypropylene (PP) shell, a commodity thermoplastic chosen for rigidity, impact resistance, and cost efficiency in protective cases. Polypropylene is chemically inert at room temperature and does not leach known endocrine disruptors like BPA or phthalates under normal use. The waterproofing comes from the case geometry, gasket seals (typically rubber or foam), and the material's inherent water resistance, not from added coatings that could degrade or release chemicals.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Polypropylene degradation and microplastic shedding
Prolonged UV exposure or thermal cycling can cause PP to become brittle and crack; damaged internal surfaces may shed small polymer particles. Risk is low under indoor storage but increases with outdoor sun exposure or extreme temperature swings.
Mold and bacterial growth inside sealed case
If moisture enters and the case is sealed without drying, fungi and bacteria can colonize internal foam or rubber. Risk is low if the seal remains intact and the case is stored dry, but improper maintenance (storing a wet camera inside) creates a closed, humid microenvironment.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Gasket material composition and off-gassing
Nanuk does not publicly disclose gasket material (rubber compound, EVA foam, or synthetic blend) or any flame-retardant or plasticizer additives within seals. No reported health complaints or testing results are available for this model's gasket.
Chemical leaching from closures, latches, or hinges
Metal latches and hinge hardware are not specified by Nanuk; if zinc alloy or painted steel is used, no test data on heavy metal leaching into liquids or skin contact is publicly available. Risk is minimal for a protective case because latches do not contact food or skin during normal use.
How is this PFAS grade calculated?
The brand's record and disclosure
Nanuk is a North American protective-case manufacturer with no public disclosure stance on PFAS, flame retardants, or other regulated chemicals in their polymer formulations. No major recalls, safety certifications, or third-party testing records are publicly documented for this specific model. The brand maintains basic compliance with North American consumer product standards (CPSIA, Health Canada) but does not market transparency around material sourcing or additive content.
How it compares in its category
Hard polypropylene cases dominate the mid-range protective-case market (Pelican, Storm Case, Nanuk); they are functionally equivalent to injection-molded ABS alternatives but lighter and more chemically stable. Unlike soft fabric camera bags or vintage leather cases, PP cases avoid mold, moisture retention, and off-gassing. The sealed-gasket design is the safety standard for waterproof cases and does not rely on problematic surface treatments.
If you buy it
Store the case in a dry, cool location away from direct sunlight to prevent polymer embrittlement over years of use; sunlight degrades PP and can cause stress cracks that compromise the seal. Do not expose the case to prolonged heat above 60°C (140°F), as PP softens and gasket adhesion can fail. Inspect gaskets annually for compression set or separation; replace the foam seal or rubber gasket if water begins pooling inside after closure. Never assume the case is waterproof indefinitely; gaskets wear out and should be treated as consumable.
