ALPS Mountaineering Torrent Dry Bag Multi-Pack
Waterproof dry bags often use PFAS coatings; brand silent on composition.
ALPS Mountaineering does not disclose PFAS use or absence in this dry bag. Waterproof coatings commonly contain PFAS; no public test data available. Contact brand for material specifics if PFAS avoidance is critical.

The full breakdown
What it's made of and why it matters
ALPS Mountaineering Torrent bags are constructed from tarpaulin or vinyl material with a waterproof coating. The waterproof function typically requires either Teflon-type coating-based or PU (polyurethane) coatings, though ALPS does not publicly specify which. Since the bag contact is external (gear protection) rather than food or skin contact, the primary concern is coating durability and potential shedding of microparticles during heavy use or aging, not direct chemical leaching into consumables.
The brand's record and disclosure
ALPS Mountaineering has no publicly available material safety disclosures, third-party certifications (such as Bluesign or OEKO-TEX), or statements on PFAS use in their waterproof coatings. No recalls or safety controversies specific to this product line have been documented in public records. The brand's silence on composition is typical of outdoor gear manufacturers but limits independent verification of chemical safety claims.
How it compares in its category
Dry bags are a lower-hazard product category compared to cookware or personal care items because contact is incidental and non-ingestion. Most competitors in this space (Osprey, Sea to Summit, NRS) similarly lack public PFAS disclosures. Dry bags with stated PU coatings may off-gas less than Teflon-type coating-coated alternatives, though neither is independently tested by ALPS. Durability and user maintenance are stronger differentiators than chemical risk.
If you buy it
Store the bag in a cool, dry location away from prolonged sunlight, which can degrade waterproof coatings and increase microparticle release. Avoid folding or compressing heavily when not in use; coatings may crack and shed. Rinse the exterior with fresh water after saltwater use to slow corrosion. Replace the bag if seams fail, coating visibly flakes, or waterproofing diminishes; this signals end-of-life, not a safety trigger but a performance indicator.
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.”
Teflon-type coating fume risk
If coating contains Teflon-type coating and bag is heated (e.g., stored in hot vehicle or near fire), decomposition is theoretically possible but unlikely in normal outdoor use. No reports of fume incidents in dry bags are documented.
Microplastic shedding from coating degradation
Waterproof coatings degrade with UV exposure and mechanical stress. Shed microparticles are unlikely to enter food or water in typical use but may accumulate in soil if bag is left in field or heavily abraded over years.
PU coating off-gassing (if present)
Polyurethane waterproof coatings can release VOCs, particularly when new. Odor typically dissipates within days to weeks; no acute toxicity is expected for outdoor storage but may be noticeable when opening sealed bag indoors.
Heavy metals in vinyl or pigments
No public records of lead, cadmium, or antimony contamination in ALPS dry bags. Vinyl formulations for outdoor gear typically do not include these unless deliberately added; no evidence exists for this brand.
Formaldehyde resin use
Dry bags do not typically use formaldehyde-based resins in their construction; this hazard class applies primarily to apparel with durable-press finishes and is not relevant to this product.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
