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 Robens.
  • We flag Fluorinated DWR coating leachates (PFAS precursors), Formaldehyde resins in polyester fabric finishes, Azo dyes in fabric coloring and Mold and bacterial growth in fabric seams and underside on the Robens and not on the Big Agnes.
  • The Big Agnes is Nylon ripstop with DWR coating (type unspecified) where the Robens is polyester/nylon tent fabric with durable water-repellent (DWR) 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 →
