NRS Expedition DriDuffel Dry Bag
Skip until NRS discloses waterproofing chemistry.
NRS Expedition DriDuffel uses PVC-coated nylon with unspecified waterproof treatment. Brand does not disclose PFAS status or provide certifications; waterproof coatings often contain PFAS-based water-repellent coating agents.

The full breakdown
What it's made of and why it matters
This dry bag uses PVC-coated nylon as its core material. PVC itself is stable when not heated, but the waterproof treatment applied to the nylon is the unknown variable. NRS does not publicly disclose whether their waterproofing uses PFAS-based chemistry (common in the industry) or non-fluorinated alternatives. The coating and stitching seals are what keep water out, but their composition drives the true safety profile of this product.
The brand's record and disclosure
NRS (Northwest River Supplies) is an established outdoor gear manufacturer with no public record of PFAS disclosure, third-party testing, or commitment to phasing out fluorochemicals in their waterproofing. The company has not faced major safety recalls related to dry bags, but their silence on waterproofing chemistry is a red flag in an industry where PFAS contamination in textiles is now documented. No certifications like GOTS, bluesign, or OEKO-TEX were found for this product line.
How it compares in its category
Dry bags with transparent PFAS-free waterproofing (silicone coatings, wax treatments) are available from competitors like Patagonia and some smaller brands, though they cost more and may not last as long. The NRS Expedition sits in the middle-market segment where PFAS-based polyurethane or Teflon-family coating coatings are still industry standard. Equivalent gear from certified suppliers (bluesign, Cradle to Cradle) exists but with trade-offs in durability or price.
If you buy it
Keep the dry bag out of direct heat and UV for extended periods, as PVC can degrade and ooze plasticizers over time. Do not machine wash or submerge in hot water; rinse gently with cool water and air-dry completely before storage. Expect 5-10 years of reliable performance if used moderately; replace when seams fail or coating visibly flakes. Store in a cool, dry place away from direct sunlight to slow degradation and minimize off-gassing of any fluorochemicals or PVC additives.
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.”
PVC leaching (phthalates, additives)
PVC-coated nylon may contain plasticizers and stabilizers that migrate into water or food contact if used to store moist items long-term. Risk is low for dry goods but increases with heat, wear, and age of the coating.
Coating degradation and microparticle shedding
Formaldehyde resins in fabric treatments
Standard for nylon textiles, but NRS does not disclose use of formaldehyde-based dyes or finishes. If present, off-gassing is minimal in dry goods storage but may occur in damp conditions.
Unknown waterproofing chemistry (non-PFAS evaluation)
NRS does not publish waterproof treatment type. Industry standard for PVC-nylon is PFAS-based polyurethane. If PFAS is used, long-term shedding into water and skin contact is possible; non-fluorinated alternatives (silicone, wax) are safer but unconfirmed here.
Flame retardant additives
No flame retardants are required or commonly added to dry bags; none are documented for this product. Risk is negligible.
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.
