Hyperfreak Fire 4/3 Chest Zip Wetsuit vs Men's R2 Yulex Regulator Front-Zip Full Wetsuit: which is safer?

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.
• We flag Formaldehyde-releasing resins (glues/seams) and Microplastics shedding from outer shell on the Patagonia and not on the O'Neill.
• The O'Neill is Neoprene/synthetic rubber with DWR coating where the Patagonia is Yulex (synthetic rubber), neoprene-free base, which is most of the difference in these two grades.
• The gap is 70 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.
