Where these two actually differ
- We flag DWR coating composition (fluorinated or non-fluorinated unknown), Coating degradation and reapplication safety and Mildew and bacterial growth if stored wet on the ALPS Mountaineering and not on the Big Agnes.
- 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 ALPS Mountaineering.
- The ALPS Mountaineering is Polyester ripstop fabric with durable water repellent (DWR) coating where the Big Agnes is Nylon ripstop with DWR coating (type unspecified), 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 →
