Men's 501 Original Thermodapt Jeans vs Men's Riggs Workwear Relaxed-Fit Work Horse Jeans: which is safer?

Where these two actually differ

• We flag Azo dyes and color fastness, Formaldehyde residues from finishing and Degradation and microfiber shedding on the Levi's and not on the Wrangler.
• We flag Azo dyes in indigo dyeing, Formaldehyde from sizing or finishing resins, Stain-resistant chemical finish composition and Dye migration or bleeding onto skin on the Wrangler and not on the Levi's.
• The Levi's is 100% cotton denim, no disclosed water-resistant treatment where the Wrangler is 100% cotton denim, 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.
