Dry Pocket Waterproof Floating Backpack Dry Bag
Skip. Waterproof coating type undisclosed, PFAS risk.
Waterproof dry bags typically use water-repellent coating coatings that may contain PFAS. The brand provides no material or treatment details, and no independent verification is available.

What Dry Pocket Waterproof Backpack Dry Bag is made of, ingredients and materials
This dry bag uses synthetic fabric (likely polyester or nylon) with an unspecified waterproof coating. The coating is the critical unknown, waterproofing in backpacks is typically achieved via polyurethane, silicone, or Teflon-family coating (Teflon-type coating/PFC) systems. Without manufacturer disclosure of which, you cannot rule out PFAS-based coatings. Synthetic base fabrics themselves (polyester, nylon) do not pose inherent leaching hazards under normal use, but the coating's chemical identity and degradation profile are opaque.
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.
Waterproof coating composition (Teflon-type coating/PFC vs. polyurethane/silicone)
Coating type is not disclosed by manufacturer. If Teflon-family coating-based, PFAS exposure risk exists during manufacturing and potentially over product lifetime; this is handled separately in PFAS grading (20/100). Polyurethane or silicone coatings carry no known PFAS hazard.
Coating degradation and microparticle shedding
Synthetic waterproof coatings degrade with UV exposure, heat, and mechanical wear. As coating breaks down, microscopic fragments may shed into water or skin contact; long-term inhalation or ingestion risk is low but not zero if coating flakes are handled or stored near food.
What’s reassuring
Formaldehyde / VOCs
No formaldehyde-based finishing or resin reports exist for Dry Bag Co dry bags. Standard polyester and nylon backpack fabrics are not treated with formaldehyde unless explicitly dyed or flame-retarded; no evidence of either here.
Source, ATSDR ↗Heavy metals
No recalls or testing data link this brand or product to azo dye or heavy metal contamination. Synthetic fabrics in dry bags are typically low-risk for pigment hazards unless marketed as bright or specialty colors with unregulated dye suppliers.
Source, FDA ↗Antimony in polyester fiber
Polyester backpack fabrics may contain trace antimony (used as a catalyst in fiber production). At normal background levels in commercial textiles, this poses no established health hazard during wear or handling; no specific risk identified for Dry Bag Co.
How is this PFAS grade calculated?
The brand's record and disclosure
Dry Bag Co has not publicly disclosed waterproof coating chemistry or provided PFAS testing/certification. No recalls or safety controversies are on record for this brand. The silence on coating composition is the primary concern; responsible waterproof gear manufacturers typically specify polyurethane, silicone, or state PFAS-free certification. The absence of such transparency is a red flag for informed purchasing, not necessarily proof of harm.
How it compares in its category
Waterproof backpacks routinely use PFC or Teflon-type coating coatings; many brands do not disclose this. Premium competitors (e.g., Ortlieb, SealLine) explicitly market PFAS-free or PFC-free alternatives using polyurethane or silicone, making their chemistry knowable at point of sale. Budget and mid-tier brands often remain silent, making Dry Bag Co typical of the opaque segment rather than an outlier. If PFAS avoidance is a priority, coated bags from brands with explicit certification may present lower concern.
If you buy it
Store the bag in a cool, dry place away from prolonged sunlight, which degrades synthetic coatings over time. Do not machine wash or expose to high heat, as these can accelerate coating breakdown and potential leaching. Inspect the seams and coated surfaces annually for cracks, peeling, or white residue; once compromised, water resistance fails and microscopic coating particles may shed. Hand wash with mild soap and air dry if needed; replace when coating visibly deteriorates (typically 3-5 years with normal use).
