What ALPS OutdoorZ High Caliber Duffel Bag is made of, ingredients and materials
The High Caliber Duffel combines nylon and polyester fabrics, both synthetic polymers chosen for strength and water resistance. ALPS applies a water-repellent coating (water-repellent coating) finish to the exterior; these coatings historically relied on PFAS chemistry, though newer non-PFAS alternatives now exist. Neither nylon nor polyester themselves leaches hazardous chemicals under normal use, but the water-repellent coating treatment remains the material concern. The bag contains no known PVC, phthalate plasticizers, or azo dyes in the base fabric.
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.
PFAS
ALPS does not disclose whether the water-repellent finish uses PFAS-based or alternative chemistry. Standard industry practice has historically favored PFAS, but absence of transparency does not confirm it. Request material specifications from the manufacturer if this is a decision factor.
Source, ATSDR ↗Mold and bacterial growth in storage
Duffel bags stored damp or in humid conditions can develop mold within seams and folds. This is a hygiene issue rather than a chemical hazard, but it can degrade the coating and fabric. Ensure the bag is fully dry before storage and keep it in a ventilated space.
What’s reassuring
Microplastic shedding from synthetic fibers
Nylon and polyester fabrics can shed microfibers during washing or abrasion. For a duffel bag, shedding is minimal under normal use (dry storage, occasional wiping), and no reported incidents exist. Risk rises only if the bag is machine washed frequently or used as apparel.
Heavy metals
No testing or recalls document lead, cadmium, or other heavy metals in ALPS duffel colorants. Commercial nylon-polyester bags sold in North America are typically subject to informal compliance with textile safety standards, but specific testing data for this model is not public.
Source, FDA ↗Flame retardants
The High Caliber Duffel is not marketed as flame-resistant and carries no FR certification. Outdoor gear bags do not routinely receive flame-retardant treatment, so none is expected. No hazard is documented.

The brand's record and disclosure
ALPS Mountaineering has not published a PFAS disclosure statement, supply-chain transparency report, or certification (e.g., BLUESIGN, OEKO-TEX) for this product line. The company does not advertise PFAS-free status or alternative water-repellent coating chemistry. No recalls or safety controversies involving ALPS duffel bags are on public record. Absence of disclosure does not confirm PFAS presence, but it prevents informed assessment of the water treatment.
How it compares in its category
Outdoor duffel bags typically use nylon-polyester blends with water-repellent coating coatings; ALPS' construction and pricing are standard for this segment. Competitors like Patagonia and Arc'teryx have begun disclosing PFAS avoidance or use of wax-based coatings, setting a higher transparency benchmark. ALPS has not matched this practice, placing it in the middle of the market on disclosure but not on hazard exposure, which remains uncertain. The actual durability and water resistance of the High Caliber are well-regarded, suggesting the water-repellent coating is effective whether PFAS or not.
If you buy it
Air dry the bag away from direct heat or flame; do not tumble dry or machine wash, as agitation can degrade the water-repellent coating. Store in a cool, dry place to extend coating life and prevent mold growth in folds. The water-repellent coating finish will diminish over 2-4 years with heavy use; reapply a commercial water-repellent coating spray (follow product instructions) or retire the bag. If PFAS presence concerns you, contact ALPS directly to request material safety data before purchase.
