Where these two actually differ
- We flag Fluorinated DWR coating (PFAS-class concern), Polyester fiber shedding (microfibers) and Mold or bacterial growth if stored wet on the Coleman and not on the The North Face.
- We flag PFAS in DWR water-repellent finish, Formaldehyde or antimicrobial resins in polyester coating, Azo dyes or heavy metals in polyester dye lots and Microfiber shedding on washing on the The North Face and not on the Coleman.
- The Coleman is polyester shell with DWR (durable water-repellent) finish where the The North Face is polyester shell with DWR water-repellent finish, 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 →
