DryPack Waterproof Roll-Top Duffle Bag
Roll-top bags often use water-repellent coating coatings. Manufacturer silence on PFAS is concerning.
Waterproof duffle bags typically receive water-repellent coating treatments, historically PFAS-based. No brand disclosure on coating chemistry or PFAS avoidance exists.

What DryPack Waterproof Roll-Top Duffle Bag is made of, ingredients and materials
DryPack uses nylon or polyester with an unspecified waterproof coating, likely a water-repellent coating (water-repellent coating) finish applied to the fabric surface. The coating is essential for waterproofing but is also the primary chemical exposure vector, its composition directly affects whether PFAS, solvents, or other synthetic chemicals leach into contact with skin or stored items. Without disclosed formulation, the coating's durability and off-gassing profile cannot be assessed from public information.

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 degradation and leaching
Unspecified water-repellent coating may contain polyurethane, acrylics, or fluorinated compounds; as the coating ages or is exposed to friction/heat, monomers and plasticizers can leach into stored items. No specific test data for DryPack is on record, but this is a known risk class for coated fabrics.
Volatile organic compound (VOC) off-gassing
Synthetic waterproof coatings typically off-gas solvents used in application (e.g., isocyanates, xylene) during the first weeks after manufacture. In a sealed or poorly ventilated storage situation, inhalation exposure is theoretically possible but typically minor; no manufacturer data on DryPack off-gassing profile is available.
Microplastics
Polyester or nylon fabrics shed microfibers when abraded or laundered. A roll-top bag experiences internal friction and external rubbing; if contents are food, cosmetics, or frequent-wash items, cross-contamination is possible. This is a category-wide issue, not specific to DryPack, but relevant to long-term use.
Source, EPA ↗What’s reassuring
Azo dyes in nylon or polyester fabric
No recalls or warnings specific to DryPack textile dyes have been reported. Nylon and polyester in outdoor bags are often dyed with azo compounds; some releases carcinogenic amines under reductive conditions (e.g., sweat + bacteria). Risk is low for bags used as intended but cannot be ruled out without material testing.
Flame retardants
No evidence that DryPack treats fabric with halogenated or phosphorus-based flame retardants. Outdoor duffle bags are not typically subject to flammability standards requiring such additives, so presence is unlikely but unconfirmed by the manufacturer.

The brand's record and disclosure
Dry Bag Co. has not made public statements about PFAS use, chemical composition, or testing of their waterproof coatings. This silence is significant because industry leaders (e.g., some outdoor gear manufacturers) now disclose water-repellent coating chemistry proactively. No major recalls or safety controversies specific to this brand are on record, but lack of transparency on coating materials means you cannot verify compliance with emerging restrictions on fluorinated compounds in textile coatings.
How it compares in its category
Roll-top duffle bags typically use polyurethane, PVC, or fluorocarbon-based water-repellent coating coatings to achieve waterproofing. Bags labeled with specific coating names (e.g., 'Parylene', 'TPU', or manufacturer certifications like Bluesign) allow informed choice; DryPack's omission leaves it in an ambiguous middle ground. Premium alternatives disclose coating chemistry or use PFAS-free alternatives; budget options often do the same out of cost considerations.
If you buy it
Inspect the bag regularly for coating cracks, peeling, or delamination, these indicate chemical breakdown and increased leaching risk. Do not expose the bag to sustained heat (e.g., direct sunlight for days, dryer heat) or solvents (acetone, alcohol), which can degrade waterproof coatings and release volatile components. If stored with sensitive items (food, cosmetics, electronics), use an internal barrier (e.g., plastic liner) to isolate contact. Consider requesting coating specifications from the manufacturer before purchase to inform your decision.
