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 Nemo Equipment.
  • We flag DWR coating composition (fluorine status unknown), Mold and bacterial growth (user-dependent) and Coating degradation and reapplication products on the Nemo Equipment and not on the Big Agnes.
  • The Big Agnes is Nylon ripstop with DWR coating (type unspecified) where the Nemo Equipment is Nylon ripstop fabric with DWR (durable water repellent) coating; OSMO fabric technology, 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 →
