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 Trespass.
- We flag PFAS in waterproof coating, Coating degradation and microplastics, Volatile organic compounds (VOCs) from coating and Mold and bacterial growth (maintenance-related, not material toxicity) on the Trespass and not on the Big Agnes.
- The Big Agnes is Nylon ripstop with DWR coating (type unspecified) where the Trespass is Polyester fabric with 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 →
