Where these two actually differ
- We flag Azo dyes and dye residues, Formaldehyde resins in finishing, Elastane (spandex) degradation and microfiber shedding and Heavy metals in dyes or pigments on the Lululemon and not on the Puma.
- We flag Azo dyes, Formaldehyde resins (finishing agents) and Microplastic shedding on the Puma and not on the Lululemon.
- The Lululemon is Nylon blend with elastane where the Puma is Cotton/polyester blend socks, no waterproofing, 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.
