Men's R2 Yulex Regulator Front-Zip Full Wetsuit vs Men's Yulex Regulator Lite Long John Wetsuit: which is safer?

Where these two actually differ

• We flag Formaldehyde-releasing resins (glues/seams) and Microplastics shedding from outer shell on the Patagonia and not on the Patagonia.
• We flag Formaldehyde resins in seam tape or elastic trim, Azo dyes in color application, Aluminum or heavy metal accelerators in rubber vulcanization and Microplastic shedding during use and washing on the Patagonia and not on the Patagonia.
• The Patagonia is Yulex (synthetic rubber), neoprene-free base where the Patagonia is Yulex (synthetic rubber), neoprene-free alternative, 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.
