Epic Back Zip Full Wetsuit vs Men's R2 Yulex Regulator Front-Zip Full Wetsuit: which is safer?

Where these two actually differ

• We flag DWR surface coating degradation and leaching, Neoprene off-gassing and volatile organic compounds and Nylon microfiber shedding during wear and washing 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 with DWR-treated nylon exterior 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 45% confidence against 72%, because it discloses less.
