Stain Resistant Repp Neck Ties Lot Of 2 Silk Made In vs H-mors Twillbi Tie 7cm: which is safer?

Where these two actually differ

• We flag PFAS in stain-resistant finish and Coating degradation and particle shedding on the Brooks Brothers and not on the Hermès.
• We flag Azo dyes and heavy-metal mordants, Formaldehyde-releasing finishing resins, Residual dye and chemical volatiles and PFAS in water-repellent or stain-resistant coatings on the Hermès and not on the Brooks Brothers.
• The Brooks Brothers is silk with stain-resistant finish (composition unspecified) where the Hermès is silk twill, which is most of the difference in these two grades.
• The gap is 50 points, wide enough that this is not a close call, and the Hermès is the one to buy.
• We are less certain about the Brooks Brothers grade, at 42% confidence against 78%, because it discloses less.
