Men's Workout Essentials Base Woven Shorts vs Men's Union Heather Amphibian 20" Boardshorts: which is safer?

Where these two actually differ

• We flag Azo dyes and heavy metal colorants, Microfiber shedding from synthetic blend and Formaldehyde resins in finishing on the Adidas and not on the Quiksilver.
• We flag Antimony catalyst residue in polyester and DWR coating degradation and microparticle shedding on the Quiksilver and not on the Adidas.
• The Adidas is Woven polyester/nylon blend, no waterproof or stain-resistant treatment specified where the Quiksilver is polyester blend with DWR water-repellent finish, 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 Adidas is the one to buy.
• We are less certain about the Quiksilver grade, at 45% confidence against 72%, because it discloses less.
