What Waterproof Duffel Bag, 70L Dry Backpack is made of, ingredients and materials
This duffel uses a roll-top fabric with an unspecified waterproof coating. The base is likely polyester or nylon, which are chemically inert when not heated. The coating itself is the concern, waterproof finishes on outdoor gear typically rely on fluorochemicals (PFAS-based), polyurethane, or silicone, each with distinct leaching and durability profiles. Without the brand naming the coating type, you cannot assess whether it will degrade, leach into contents, or off-gas volatile organic compounds during storage or sun exposure.
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.
Waterproof coating leachables (unspecified chemistry)
Brand does not disclose whether the coating is PFAS-based, polyurethane, or silicone. If PFAS-based, fluorochemicals may leach into stored items over time, especially if contents are wet or the bag is heated. If polyurethane, volatile organic compounds can off-gas during storage and transport.
Volatile organic compound (VOC) off-gassing
Most unspecified waterproof coatings on roll-top duffels emit VOCs, particularly in the first weeks of use and storage in warm, enclosed spaces. This is a temporary discomfort and inhalation risk rather than a long-term toxicity hazard, but ventilation is necessary.
Coating adhesion and durability loss
Without brand specification of coating type and adhesion testing standards, the waterproof layer may degrade faster under UV, friction, or repeated flexing. As the coating breaks down, the fabric becomes water-permeable and may shed microparticles or leach residual coating chemicals into stored contents.
What’s reassuring
Polyester/nylon base fabric degradation
Polyester and nylon are chemically stable under normal use. No documented leaching of antimony or other heavy metals from this product. Risk arises only if the waterproof coating degrades and exposes the base fabric to mechanical breakdown and shedding of microfibers.
Label and trim contaminants (dyes, adhesives)
No specific information on azo dyes, formaldehyde resins, or adhesive chemistry in printed labels or webbing trim. This is a standard undisclosed risk for budget outdoor gear and unlikely to transfer to skin or food unless direct contact is prolonged.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand has no public record of safety disclosures, PFAS commitments, or third-party certifications (Bluesign, GOTS, Oeko-Tex) for this product line. The brand's silence on waterproof coating chemistry is standard for mass-market duffel manufacturers but represents a transparency gap. No product-specific recalls or contamination incidents are documented in public databases. This lack of information is not evidence of safety, but rather absence of accountability.
How it compares in its category
Most budget-tier dry bags (especially roll-top designs) use either PFAS-coated fabrics or solvent-heavy polyurethane coatings to achieve waterproofing. Higher-end alternatives (Ortlieb, SealLine) disclose PFAS-free silicone or PU chemistry and undergo independent testing. This product sits in the undisclosed middle, likely functional for water resistance but with unknown chemical inputs. You are trading transparency for price.
If you buy it
Store the bag in a well-ventilated space for the first 2-4 weeks to allow any volatile off-gassing to dissipate. Avoid prolonged direct sunlight or heat above 60C (140F), which can accelerate coating breakdown. Do not store food or sensitive items directly against the interior coating; use a secondary waterproof liner. Wash the exterior only with cool water and mild soap; harsh detergents or heat will degrade the waterproof layer faster. Replace the bag if the coating begins to crack, peel, or smell like solvents, as this indicates loss of barrier integrity.
