What Amazon.com: geckobrands Valuables Wh is made of, ingredients and materials
This product is nylon fabric with an unspecified waterproof coating applied to achieve water resistance for the bag and dry bag. Nylon itself is a polyamide plastic that does not inherently leach problematic chemicals under normal use, but the waterproof treatment is the critical unknown. Geckobrands does not disclose whether the coating is polyurethane-based, acrylic, silicone, or Teflon-type coating-derived, which determines whether PFAS or other volatile organics are present. Without this information, the actual chemical profile of the product cannot be assessed.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.

No PFAS disclosure
No public statement from the brand about PFAS in this product.
PFAS
The unspecified waterproof coating likely includes polyurethane or acrylic-based compounds that off-gas volatile organic compounds (VOCs) during curing and storage. Off-gassing diminishes over time but is highest in the first weeks of ownership.
Source, ATSDR ↗Coating degradation and secondary leachate
Nylon waterproof bags are prone to coating breakdown under UV exposure, heat cycling, and mechanical stress. As the coating degrades, underlying nylon fibers and any residual treatment chemicals may contact contents or skin.
What’s reassuring
Microplastic shedding from fabric
Nylon bags can shed microfibers during use and washing, though this is more significant for textiles worn against skin. For a phone tote, direct human exposure risk is low, but shedding into water during cleaning is possible.
Metal hardware corrosion or leaching
The product description does not specify the composition of straps, zippers, or fasteners. If uncertified metal hardware is used, zinc or nickel plating could corrode under moisture exposure and leach; no data on this product's hardware is publicly available.
Formaldehyde / VOCs
Industrial nylon production may involve formaldehyde-releasing compounds or azo dyes, but modern production typically minimizes these. No recalls or warnings specific to Geckobrands nylon bags have been reported for this hazard.

The brand's record and disclosure
Geckobrands maintains a silent stance on waterproof coating chemistry and does not publish material safety data sheets or third-party certifications for their bags. No formal recalls or safety violations have been recorded for this specific product. The brand does not appear to have adopted transparency initiatives common to higher-tier outdoor gear makers, such as Bluesign certification or PFAS avoidance commitments, making it difficult for consumers to verify what waterproofing agent was used.
How it compares in its category
Waterproof fabric bags in this price and function tier typically use either Teflon-type coating-based coatings (which pose PFAS concerns), PU-based coatings (which off-gas volatile organics during curing but stabilize after), or silicone treatments (lower PFAS risk but less durable). Geckobrands does not specify which approach was chosen, placing this product in the middle of a poorly transparent segment. Premium competitors like Sea to Summit and Ortlieb disclose their coating chemistry; budget alternatives often use similar opacity but cost less.
If you buy it
Air the bag thoroughly before first use to allow any volatile organics from the coating to off-gas, ideally in a well-ventilated space for 24-48 hours. Avoid storing the bag with food or clothing directly against the coated surface for extended periods; use the bag for its intended short-term phone and valuables protection rather than permanent storage. Inspect the seams and coated surface periodically for peeling, cracking, or degradation, particularly after exposure to direct sunlight or heat, as coating breakdown can expose underlying nylon and reduce waterproofing. Do not use in high-heat environments (car dashboards, near radiators) as coatings can soften and leach.
