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 Hyperlite Mountain Gear.
  • We flag UV degradation of nylon and silicone coating, Silicone coating delamination and Nylon fiber shedding and microplastic generation on the Hyperlite Mountain Gear and not on the Big Agnes.
  • The Big Agnes is Nylon ripstop with DWR coating (type unspecified) where the Hyperlite Mountain Gear is Silnylon (nylon + silicone coating); Dyneema fabric, 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 →
