Where these two actually differ

  • We flag Fluorinated DWR coating residues (PFOA/PFCs in historical treatments), Mold and bacterial growth in stored damp fabric and Heat sensitivity of DWR-coated nylon near fire or stove on the Big Agnes and not on the Zpacks.
  • We flag Durable water repellent (DWR) coating composition, unspecified, Coating degradation and delamination over time, Polyester scrim fiber shedding and microfiber release and Bacterial or mildew growth in seams and coating on the Zpacks and not on the Big Agnes.
  • The Big Agnes is Nylon ripstop with DWR coating (type unspecified) where the Zpacks is Proprietary DCF (Dyneema composite fabric) with unspecified waterproof coating, which is most of the difference in these two grades.
  • These two are level, close enough that price and fit should decide it rather than our grade.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
