Otter Box Waterproof Drybox Storage Secure Gear Storage Outdoor
Waterproof drybox; PFAS status in coatings unknown, no disclosure.
OtterBox dryboxes use waterproof treatments and seals to protect contents, but the brand does not disclose PFAS in materials or coatings. Waterproof polymers often contain PFAS; exact composition unclear.

The full breakdown
What it's made of and why it matters
OtterBox dryboxes are injection-molded polypropylene (PP) or similar rigid thermoplastics with polyurethane or silicone-based waterproof gasket seals. The polymer shell itself is generally inert and food-contact safe under normal conditions. The waterproof coatings or gasket materials may contain PFAS to achieve water repellency, though OtterBox does not publicly disclose this. Since this is a storage container used for dry goods and equipment rather than food or liquids in prolonged contact, direct leaching risk is lower than for cookware or food-contact plastics.
The brand's record and disclosure
OtterBox is a U.S. manufacturer known for rugged protective gear and cases; they do not publish PFAS policy statements or third-party chemical certifications for their drybox line. No major recalls for chemical hazards have been publicly reported for this product category. The brand does not market their products as PFAS-free or chemical-certified, and transparency on waterproof coating chemistry is absent from public materials.
How it compares in its category
Rigid plastic dryboxes from major outdoor brands (Pelican, OtterBox, Rite Hite) typically use similar PP or ABS shells with synthetic gaskets. OtterBox products are mid-to-premium priced and well-regarded for durability and water seal integrity. Few manufacturers in this category disclose PFAS or provide chemical certifications, making OtterBox typical rather than better or worse than alternatives.
If you buy it
Store dry goods, electronics, and gear only; avoid prolonged contact with liquids, especially acidic or oily foods. Do not heat the box or its contents inside it (e.g., microwaving). Inspect gaskets annually for cracks or hardening and replace if seals degrade, as loss of waterproofing may increase risk of mold or mildew inside. Keep the box clean and dry inside to prevent bacterial or fungal growth in humid conditions.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Gasket/seal degradation and microbial growth
Polyurethane and silicone gaskets can crack, harden, or degrade over years of UV exposure or temperature cycling. Once seals fail, moisture and trapped organic matter can support mold, mildew, or bacterial growth if the box is not dried regularly.
Polymer off-gassing (VOC) in enclosed spaces
Polypropylene and injection-molded plastics can emit low levels of volatile organic compounds (VOCs) especially in warm or enclosed conditions. Risk is minimal for outdoor/open storage but may accumulate if contents are sealed for extended periods in high heat.
Leaching from gasket materials into stored goods
Silicone or polyurethane gaskets may release small amounts of uncrosslinked oligomers or additives if in contact with oily, acidic, or alcohol-based stored items. Risk is low for typical dry equipment but increases with food storage or long contact times.
PFAS in waterproof coatings or gaskets
Waterproof dryboxes commonly use PFAS-containing treatments in gaskets or coatings to achieve water repellency. OtterBox does not disclose coating chemistry, so PFAS presence is unconfirmed but plausible given the product category.
Heavy metals in pigments or colorants
Polypropylene used in OtterBox dryboxes is typically colored with modern organic or inert pigments. No recalls or public reports of lead or cadmium in colorants for this product line; risk is minimal for closed storage use.
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.
