Stormtech Waterproof Gear Holdall Bag
Skip until brand discloses waterproof treatment chemistry.
Waterproof Technologies does not disclose coating type or PFAS status on this holdall. Standard waterproof treatments often contain PFAS; without transparency, risk remains unclear.

The full breakdown
What it's made of and why it matters
Stormtech's Waterproof Gear Holdall uses an unspecified synthetic fabric with a waterproof coating of undisclosed chemistry. The coating is the critical unknown: traditional waterproof treatments on outdoor gear rely on PFAS (per- and polyfluorocarbon compounds) for durability and water repellency, but some brands now use PFOA-free or alternative systems. Without Waterproof Technologies publishing treatment details, you cannot assess whether this bag uses legacy PFAS, newer fluorine-free repellents, or wax-based alternatives. The fabric substrate itself (likely polyester or nylon) poses no established hazard if uncoated, but the coating's chemical identity determines your actual exposure risk.
The brand's record and disclosure
Waterproof Technologies has not published public documentation on its waterproof coating chemistry, PFAS use, or compliance with PFAS-restriction regulations (such as EU ZDHC Gateway or similar standards). No major product recalls or safety warnings are recorded for this holdall line. The brand's silence on treatment specifics is notably different from competitors (such as Patagonia, Arc'teryx, or even mainstream outdoor brands) who increasingly disclose fluorine-free or PFAS-phasing commitments. This lack of transparency is a red flag for consumer preference but does not confirm a safety violation.
How it compares in its category
Waterproof holdalls and duffels on the market range from legacy PFAS-coated versions (cheaper, proven but persistent) to PFOA-free Teflon-family coating systems and fully fluorine-free alternatives (wax, polyurethane). Stormtech's refusal to specify places it in the murky middle: you cannot determine whether it is more conservative than budget rivals or simply opaque. Brands with published PFAS-free certifications (such as certain Decathlon or REI Co-op lines) offer clearer purchase assurance, though often at comparable or lower cost.
If you buy it
Contact Waterproof Technologies directly and request written confirmation of the waterproof coating type (fluorine-free, PFOA-free, or traditional PFAS) before purchase. Store and use the bag in well-ventilated spaces; off-gassing of coating chemicals is minimal at room temperature but can release more volatile compounds if exposed to heat (car dashboards, direct sunlight for extended periods). Wash the exterior gently with cool water and mild soap; avoid dry cleaning solvents or heat treatment. Replace the bag if the coating visibly degrades (peeling, cracking, white residue) as this may indicate breakdown of the chemical treatment and unpredictable particle or vapor release.
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.”
Coating off-gassing or degradation products
Waterproof coatings (whether PFAS or fluorine-free alternatives) can release volatile organic compounds or shed particles if the coating degrades over time or is exposed to heat/UV. No specific off-gassing data is published for this product.
Heavy metals in pigments (if printed branding/logos)
Fabric dyes and printed logos on outdoor gear can occasionally contain lead or cadmium in lower-income manufacturing regions, though major brands typically test for this. No specific contamination reports exist for Stormtech holdalls.
Mold/bacterial growth in use
Waterproof bags trap moisture if not fully dried after exposure to water; prolonged dampness can encourage mold or bacterial biofilm inside seams or corners, especially in warm climates. This is a use hazard, not a manufacturing one.
Allergic contact dermatitis from coating or dyes
Undisclosed waterproof treatments or reactive dyes can trigger contact dermatitis in sensitive individuals, particularly if the bag contacts bare skin for extended periods or if sweat activation of residual chemicals occurs.
PFAS bioaccumulation (if PFAS-based coating)
If this holdall uses traditional PFAS waterproofing, the coating will shed persistent fluorochemicals into water and soil over its lifetime and will not degrade. This is included for context but graded separately in your PFAS assessment.
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.
