Outdoor Products Watertight Gear Expandable 40L White Dry Bag
Skip. Waterproof coating unspecified, no PFAS transparency.
Dry bags typically use water-repellent coating or PFC coatings for water resistance. Outdoor Products provides no material or PFAS disclosure, limiting your ability to make an informed choice.

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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Phthalate leaching (PVC plasticizer migration)
If this bag is PVC, dibutyl phthalate (DBP) or similar plasticizers are likely present to keep the material flexible. Leaching increases with heat, skin oils, and prolonged contact. Risk is low for occasional use but rises if used to store wet clothing against bare skin for hours.
Waterproof coating degradation and off-gassing
PVC and TPU coatings (especially solvent-applied ones) can off-gas volatile organic compounds (VOCs) during and shortly after manufacturing. The unspecified coating makes it impossible to assess if PFAS, isocyanates, or other respiratory irritants are present. New bags may smell; ventilate before use indoors.
Microplastic shedding from coating wear
As the waterproof coating flexes and degrades over years of use, small particles may detach. If the bag contacts food or drinking water directly, microplastic ingestion is a non-zero risk. Use an inner liner for food storage.
What’s reassuring
Heavy metals
The white pigmentation is likely titanium dioxide (TiO2), which is stable and low-risk. No public testing or recalls have identified heavy metal contaminants in Outdoor Products dry bags, but the brand's lack of testing disclosure means this remains unverified.
Source, FDA ↗Formaldehyde / VOCs
Dry bags are usually all synthetic (PVC or TPU) with minimal fabric. If nylon or polyester reinforcement is present, formaldehyde-based resins are possible but unlikely to off-gas significantly into the bag interior. No established risk for this product.

What it's made of and why it matters
This dry bag is constructed from either PVC (polyvinyl chloride) or TPU (thermoplastic polyurethane), materials chosen for water resistance. Both require waterproof coatings or lamination to function, and the brand has not disclosed which coating is used. PVC itself can leach plasticizers (phthalates) under heat or prolonged contact with skin oils; TPU is more chemically stable but still depends on its coating. The unspecified coating is the critical unknown, it may contain PFAS, which the brand has not addressed.
The brand's record and disclosure
Outdoor Products has published no transparency statements on waterproof coating chemistry, PFAS use, or material certifications for this product line. The brand does not appear in major sustainable gear databases or third-party testing registries. No recalled safety issues have been documented for this specific product, but the silence on coating disclosure is a red flag in an industry where PFAS-free alternatives exist.
How it compares in its category
Dry bags span a wide spectrum, budget models (like this one) typically use PVC or TPU with unspecified coatings, while premium brands (e.g., Patagonia, Klattermusen) disclose PFAS-free or recycled materials and submit to third-party testing. Mid-range alternatives from Sea to Summit or Ortlieb publish coating specs. This product sits in the lower-disclosure tier, where material safety is assumed rather than verified.
If you buy it
Avoid prolonged skin contact with the interior if storing items like wet clothes or swimwear; line it with cotton if needed to minimize phthalate or coating exposure. Do not expose to direct sunlight for extended periods, as UV can degrade PVC and increase leaching. Inspect the seams and coating annually for cracks or peeling; a degraded bag should be replaced. Wash the exterior occasionally with cool water and mild soap, not hot water or solvents.
