Where these two actually differ

  • We flag PFAS in DWR coating, Neoprene degradation and microplastic shedding and Bacterial or fungal growth if not maintained on the O'Neill and not on the Patagonia.
  • The O'Neill is Neoprene/synthetic rubber with DWR coating where the Patagonia is Yulex (synthetic rubber, PTMEG-based), neoprene-free, which is most of the difference in these two grades.
  • The gap is 45 points, wide enough that this is not a close call, and the Patagonia is the one to buy.
  • We are less certain about the O'Neill grade, at 42% confidence against 72%, because it discloses less.

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 →
