Women's Oasis PureLuxe High-Waisted Pocketed Kick Flare vs Women's Chill Knit Mid-Rise Ribbed Tights: which is safer?

Where these two actually differ

• We flag Azo dyes and synthetic colorants, Formaldehyde resins (finishing agents) and Microfiber shedding from synthetic blend on the Fabletics and not on the Nike.
• We flag Formaldehyde resins (finish and dye-setting), Azo dyes and heavy metal dye contaminants, Microfibre shedding (synthetic textile degradation) and Antimony in polyester on the Nike and not on the Fabletics.
• The Fabletics is polyester blend fabric, standard construction where the Nike is Nylon/polyester knit blend, no waterproofing or coating disclosed, 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.
