What Waterproof Duffel Bag is made of, ingredients and materials
Dry Bag Co. duffel uses fabric with an unspecified waterproof coating. Most waterproof fabrics rely on either polyurethane (PU), silicone, wax, or fluorocarbon treatments. Fluorocarbon coatings are effective water repellents but often contain legacy PFAS or PFAS replacements that leach slowly into contact materials and sweat. Without disclosure from the brand, the actual chemistry remains opaque, making full risk assessment impossible.
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.
PFAS
Unspecified waterproof coating likely contains fluorocarbons or PFAS-based compounds; direct skin contact and sweat exposure over time may result in slow dermal absorption. Risk tier reflects lack of brand disclosure rather than confirmed contamination.
Source, ATSDR ↗Coating degradation and microplastic shedding
Repeated washing, UV exposure, or mechanical wear of waterproof coatings can shed microscopic polymer fragments into sweat, water, or contact surfaces. Dry Bag Co. does not specify coating durability or replacement guidance.
Volatile organic compound (VOC) off-gassing
Waterproof polyurethane or solvent-applied coatings may emit low levels of solvents or catalysts during manufacturing and early use, particularly in warm or enclosed spaces. Off-gassing typically diminishes within days to weeks but is not quantified for this product.
Mold and bacterial growth from moisture retention
Waterproof coatings can trap moisture inside the bag if ventilation is poor, creating conditions for mold or odor-causing bacteria. Proper drying and periodic airing are essential to mitigate this non-chemical hazard.
What’s reassuring
Fabric treatment chemical residues
Base fabric may carry formaldehyde resins or azo dyes if not specified as natural fiber or organically grown. No documentation available for Dry Bag Co. duffels; assume standard textile processing unless certified otherwise.
How is this PFAS grade calculated?
The brand's record and disclosure
Dry Bag Co. has not publicly disclosed the waterproof coating chemistry, certifications (such as bluesign, Cradle to Cradle, or OEKO-TEX), or any commitment to PFAS-free alternatives. No recall history or contamination incidents are publicly documented for this brand. The silence on coating composition is a significant red flag in an industry where responsible manufacturers increasingly specify non-fluorinated options or third-party test results.
How it compares in its category
Most commercial waterproof duffels use fluorocarbon or polyurethane coatings; some premium brands (e.g., Patagonia) have begun phasing to PU-only or wax-coated natural fabrics with full disclosure. Dry Bag Co. sits in the middle of the market without transparency, making it harder to compare to either budget (often untested) or eco-certified peers. Price and warranty information would help contextualize the risk-benefit, but are not provided here.
If you buy it
Avoid prolonged skin contact, especially if damp or warm (promotes leaching). Do not store food or cosmetics inside without a sealed inner container. Wipe exterior with a damp cloth rather than machine washing, which may degrade the coating and release particles. Before purchase, contact the brand directly and request the Safety Data Sheet (SDS) for the waterproofing agent; silence after 2 weeks is a valid reason to choose a competitor.
