Dry Pocket Waterproof Floating Backpack Dry Bag
Skip until brand discloses waterproof coating composition.
Dry bags typically use water-repellent coating coatings that often contain PFAS. Brand provides no material or PFAS information. Unknown coating type raises concern.

The full breakdown
What it's made of and why it matters
Dry Pocket bags use a synthetic fabric (likely polyester or nylon) with an applied waterproof coating of unspecified chemistry. Waterproof coatings on textiles are commonly formulated with Teflon-family coating (Teflon-type coating or polyfluorinated compounds) or polyurethane; the brand has not disclosed which. This matters because Teflon-type coating-based coatings raise PFAS exposure risk, while polyurethane coatings carry volatilization and durability concerns. Without material transparency, actual chemical hazard cannot be fully assessed.
The brand's record and disclosure
Waterproof Technologies has not published public documentation on coating chemistry, PFAS testing, or third-party certifications (such as OEKO-TEX or bluesign). No major recalls or chemical safety controversies are on record for this specific product line. The brand's silence on waterproofing chemistry is typical of smaller outdoor gear manufacturers but falls short of industry best practice, making independent hazard assessment difficult.
How it compares in its category
Dry bags occupy a niche where waterproofing is essential; most competitors (including premium brands) also use undisclosed coatings or rely on Teflon-type coating-based systems. Higher-transparency alternatives exist (e.g., brands explicitly stating polyurethane or PVC construction), but Dry Pocket is priced competitively for recreational use. This product is neither exceptionally transparent nor notably worse than category peers in disclosure.
If you buy it
Keep the bag away from prolonged heat (do not machine wash in hot water; air dry only) to avoid coating breakdown or fume release. Inspect seams and coating annually for cracks, peeling, or whitening; discard if structural integrity fails, as waterproofing loss indicates coating degradation. Store in a cool, dry place and avoid contact with solvents or rough abrasion. If PFAS exposure is a personal concern, request material safety data from the manufacturer before purchase.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Waterproof coating volatilization (polyurethane or Teflon-type coating-based)
If coating contains polyurethane, heat or UV exposure may initiate off-gassing of volatile organic compounds or isocyanate residues. No testing on record for this product; risk is inherent to the category and depends on coating formulation and storage conditions.
Coating degradation and microplastic release
Waterproof coatings degrade over time with mechanical wear, UV exposure, and flexing. Peeling or flaking coating can shed particles into contents or environment; no specific durability data published for Dry Pocket bags.
Dye migration or formaldehyde in synthetic textile base
Synthetic fabric base (polyester/nylon) is not inherently formaldehyde-containing unless treated with wrinkle-resist finishes. No evidence that Dry Pocket applies such treatments, but no explicit certification excludes them either.
Seam adhesive or laminate delamination
Waterproof bags rely on glued seams and laminated layers. Adhesive composition is typically undisclosed; long-term adhesive failure can compromise waterproofing and release adhesive particles.
PFAS in waterproof coating (Teflon-family coating-based)
Graded separately at 40/100; unconfirmed but statistically common in this product category. Brand silence on composition suggests no testing or transparency commitment.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
