Outdoor Products Ultimate Dry Sack 3-Pack
Likely uses PFAS-based water-repellent coating. Brand won't confirm.
Outdoor Products won't disclose what waterproof coating they use on this dry sack or whether it contains PFAS. Most waterproof textiles rely on PFAS treatments, but no testing data exists for this model.

What Outdoor Products Ultimate Dry Sack 3-Pack is made of, ingredients and materials
Outdoor Products Ultimate Dry Sacks are constructed from nylon or polyester fabric with an unspecified waterproof coating. The coating is the chemical weak point, waterproof textiles typically rely on water-repellent coating (water-repellent coating) finishes, historically PFOA/PFAS-based, though some modern alternatives exist. Nylon and polyester themselves are chemically stable in normal use, but the coating's identity and degradation pathway are unknown for this product.
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.
water-repellent coating chemistry (fluorinated or fluorine-free unknown)
Nylon/polyester dry sacks typically use water-repellent coating finishes; fluorinated versions carry PFAS exposure risk on skin contact and during washing. Outdoor Products does not disclose whether their coating is PFAS-based or an alternative, making assessment of exposure likelihood impossible without laboratory analysis.
Coating degradation and microparticle shedding
As the waterproof coating ages, flaking or peeling releases microparticles that may contain coating polymers and residual fluorochemicals (if PFAS-based). This risk increases with UV exposure and mechanical wear, particularly in sun-exposed storage or repeated washing.
What’s reassuring
Azo dyes in polyester or nylon fabric
No recalls or complaints on record for Outdoor Products dry sacks regarding azo dye toxicity. Standard nylon and polyester textiles manufactured to Oeko-Tex or similar standards minimize this risk, but Outdoor Products does not publish dye or dyeing certifications.
Antimony in polyester
Antimony (catalyst residue) in polyester fabric is regulated in many markets but not formally banned in the US. No specific hazard reports exist for Outdoor Products dry sacks. Exposure is minimal unless fabric is chewed or ingested.
VOC off-gassing from adhesives or solvents in coating application
Polyurethane or other waterproof coating adhesives may release trace volatile compounds during manufacture. No off-gassing complaints are on record for this brand or product line, and typical use (outdoor, open-air) minimizes inhalation exposure.
How is this PFAS grade calculated?
The brand's record and disclosure
Outdoor Products has not published materials certifications, PFAS sourcing statements, or independent testing results for this product line. The brand remains silent on whether water-repellent coating coatings use fluorinated or fluorine-free chemistry. This absence of disclosure is notable in a category where competitors increasingly communicate coating composition due to consumer and regulatory pressure around PFAS.
How it compares in its category
Dry sacks are a commodity item; Outdoor Products is a budget-tier brand competing on price rather than material transparency. Premium outdoor brands (e.g., Patagonia, Sea to Summit) increasingly use PFAS-free water-repellent coating or disclose fluorinated chemistry. Outdoor Products' silence places it below the transparency baseline now common in performance textiles, though the functional performance of budget dry sacks is largely equivalent.
If you buy it
Avoid prolonged skin contact if you have sensitive skin or chemical sensitivities; wash hands after handling. Do not heat-treat or machine-wash at high temperatures, as coating breakdown can accelerate chemical leaching. Inspect coating annually for flaking, peeling, or discoloration; replace the sack if the waterproof layer visibly degrades. Store in a cool, dry place to slow coating oxidation.
