NANUK 935 Waterproof Hard Case with Wheels
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes polypropylene, 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’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.
Microplastic shedding from mechanical wear
Repeated opening/closing cycles and wheel friction on polypropylene can generate micro-particles over years of use. Risk is low for external case handling but relevant if internal surfaces contact food or unprotected equipment; not a typical concern for camera gear storage.
Off-gassing from injection molding residues
New polypropylene cases may emit minor volatile organic compounds (VOCs) during the first weeks of use, especially if stored warm. This is normal for PP but typically mild; airing the case before first equipment storage minimizes any odor transfer.
Mold or bacterial growth in sealed wet environment
If the case is sealed while damp or stored in high humidity, interior surfaces and closed gaskets can harbor mold or mildew, creating respiratory irritant odors. This is a maintenance issue rather than a manufacturing defect; proper drying before closure prevents it.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Gasket/seal material composition (unknown)
Nanuk does not disclose the material of included gaskets or wheel components. Common seal materials (synthetic rubber, silicone) are low-risk, but degradation can release odors. No hazard reported; full composition transparency is lacking.
Lead
Nanuk's printed branding on the case exterior has not been tested or disclosed. Printing inks on polypropylene are generally low-toxicity, and consumer contact is minimal; no established risk for this product.

What it's made of and why it matters
The NANUK 935 is injection-molded polypropylene (PP), a thermoplastic with relatively low toxicity risk compared to other polymers. Polypropylene does not contain BPA, phthalates, or inherent heavy metals in its base resin. The case's waterproof rating comes from mechanical seals (gaskets, latches) and the material's inherent water resistance, not surface coatings, so there is no risk of coating degradation releasing hidden chemicals into contact with your equipment.
The brand's record and disclosure
Nanuk does not publish formal safety certifications, material disclosures, or chemical restriction statements on this product line. No recalls or safety complaints appear in public databases for the 935 model. The brand maintains silent on PFAS and other hazard management, which is typical for hard-case manufacturers but means reliance on material properties rather than brand assurance.
How it compares in its category
Polypropylene hard cases are the industry standard for camera protection and carry fewer chemical risks than fabric-lined or foam-padded alternatives, which may off-gas or retain flame retardants. The 935's sealed construction and wheeled design place it in the mid-to-premium segment; competitors like Pelican often use similar PP construction with comparable safety profiles. The main differentiation in this category is longevity of seals and hinge durability rather than chemical safety.
If you buy it
Keep the rubber gaskets clean and dry between uses to prevent mold growth and ensure long-term waterproof integrity. Avoid storing in direct sunlight for extended periods, as polypropylene can become brittle under UV exposure. Do not expose the case to temperatures above 60°C (140°F), as PP may warp; avoid placing near heaters or in hot vehicles. Replace gaskets or hinges if they crack or harden, typically every 3-5 years depending on use frequency.
