ALPS Mountaineering · Waterproof Sports Bags
ALPS Mountaineering Torrent Backpack
ALPS does not disclose PFAS or water-repellent coating chemistry; moderate risk typical for coated packs.
ALPS Mountaineering does not publicly state whether this pack uses PFAS-based water-repellent coating treatment. Most outdoor backpacks use water-repellent coating finishes, commonly PFAS-containing, but this brand has not disclosed specifics.

The full breakdown
What it's made of and why it matters
The Torrent is constructed from nylon fabric treated with a water-repellent coating (water-repellent coating) coating. water-repellent coating coatings historically relied on PFAS-based chemistry (PFAS "forever chemicals") for water beading, though some manufacturers have shifted to fluorine-free alternatives. ALPS Mountaineering has not publicly disclosed which chemistry they use, so the specific fluorochemical profile of this pack cannot be verified from available information.
The brand's record and disclosure
ALPS Mountaineering does not maintain a public chemical disclosure policy or PFAS commitment on record. The company has not responded to known requests for transparency on fluorochemical use in their coated gear. No recalls or established safety controversies specific to ALPS packs have been documented in consumer safety databases.
How it compares in its category
Nylon backpacks with water-repellent coating coatings are the industry standard for weather protection. Most major brands in this price tier (REI Co-op, Osprey, Arc'teryx) similarly do not fully disclose water-repellent coating chemistry, though some offer PFAS-free product lines. The Torrent sits in a middle-ground position: functional and durable, but with the same transparency gap as most conventional outdoor packs.
If you buy it
Wash sparingly using cold water and mild soap to avoid accelerating coating wear; do not machine dry or expose to high heat, as this degrades the water-repellent coating layer. Inspect seams and coating annually for breakdown; reapply fluorine-free water-repellent coating treatments if water no longer beads. At end of life, check with local textile recyclers or ALPS directly for take-back options, as PFAS-coated textiles should not enter standard landfill or incineration streams.
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.”
water-repellent coating degradation and re-treatment
Nylon water-repellent coating coatings typically remain effective for 2-4 years depending on use and care. As the coating breaks down, water beading diminishes; users may respond by applying aftermarket water-repellent coating sprays, which may introduce additional chemicals including PFAS-based alternatives if not explicitly fluorine-free.
Formaldehyde resins in nylon fabric
No specific recalls or test results for formaldehyde resins in ALPS Mountaineering packs are on record. Nylon fabric can carry trace formaldehyde from manufacturing, though levels in outdoor gear are rarely of concern after airing.
Azo dyes in nylon
No documented issues with azo dyes in ALPS packs. Nylon fabric can be dyed with both restricted and unrestricted azo compounds, but consumer reports and independent testing specific to this product are not available.
Microplastics shedding
Nylon textiles shed microfibers during washing and abrasion. While not a hazard to the user, repeated laundering of the Torrent will contribute microplastics to wastewater; minimize washing frequency to reduce shedding.
Heavy metals in dyes or coatings
No recalls or test reports documenting lead, cadmium, or other heavy metals in ALPS packs are on record. Nylon products are not commonly associated with heavy metal contamination in the coating or dye layers.
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.
