Black Hole Duffel 70L Patagonia
A water-repellent or grease-resistant treatment of unstated chemistry, with a brand PFAS statement we have not verified.
Patagonia says 100% of its new products from Spring 2025 are made without intentionally added PFAS. We record that as an unverified brand claim. Its record describes a water-repellent or grease-resistant treatment of unstated chemistry, which is still counted.

What Black Hole Duffel 70L Patagonia is made of, ingredients and materials
The Black Hole Duffel is constructed from nylon ripstop, a tightly woven synthetic fabric reinforced with a crosshatch grid to prevent tears. The waterproofing comes from a water-repellent coating (water-repellent coating) treatment applied to the surface, which sheds water without creating a plastic film. Nylon itself is chemically stable and does not leach into contents under normal conditions; the water-repellent coating chemistry is the variable element requiring disclosure.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Patagonia states PFAS-free intent, but the specific water-repellent coating chemical (likely fluorocarbon-based but not PFAS-chain) is not publicly named for this product. No alternative water-repellent coating chemistry fully eliminates water repellency questions; this is a category-wide limitation.
Source, ATSDR ↗Nylon Degradation and Microfiber Release
Nylon ripstop can shed microfibers if abraded or washed repeatedly. This is a slow process under normal packing and storage, but extended outdoor use or aggressive washing accelerates fiber loss. Frequency of washing and storage conditions directly affect this risk.
What’s reassuring
Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
Formaldehyde / VOCs
No formaldehyde-based dye treatments or finishing resins have been disclosed or are typical for nylon ripstop in this product class. Patagonia's dyeing standards typically exclude high-risk finishes, but independent verification for this specific product is not on record.
Source, ATSDR ↗Heavy metals
Black nylon dyes can theoretically contain cadmium or lead in low-cost production; Patagonia's manufacturing standards and certifications (Fair Trade Certified factories) make this unlikely, but not independently verified for this specific batch.
Source, FDA ↗Adhesive or Seam Leachables
Seams and closures may use adhesives or thread treatments; Patagonia does not disclose these for this product, but the brand's commitment to supply chain transparency and factory audits reduces risk relative to unbranded alternatives.
How is this PFAS grade calculated?
The brand's record and disclosure
Patagonia has publicly committed to eliminating intentional PFAS from its product line and has communicated this stance transparently. The company provides repair services and encourages reuse, which reduces lifecycle impact. However, the specific water-repellent coating formulation used on this model has not been independently verified or disclosed in accessible detail; Patagonia's statement covers intent but not confirmatory chemistry data for individual products.
How it compares in its category
Nylon ripstop duffels with water-repellent coating treatment are the industry standard for lightweight, packable luggage. Alternatives include PVC-coated canvas (durability advantage but heavier and less packable) and polyester with polyurethane coatings (similar hazard profile to this product). Patagonia's version ranks above average for transparency relative to mass-market competitors, though still below the disclosure level of independent certifications like Bluesign or GOTS.
If you buy it
Rinse with cool water and mild soap to preserve the water-repellent coating treatment; avoid machine washing and high heat. Do not dry-clean or use solvents, which can degrade the coating. The water-repellent coating will diminish over time (typically 2-3 years of heavy use); Patagonia offers re-proofing services or you can purchase commercial water-repellent coating sprays. Store dry and uncompressed to extend fabric life and prevent mildew.
