Where these two actually differ
- We flag Water-resistant coating composition (unspecified chemistry), Azo dyes (synthetic colorants), Coating degradation and microplastics on washing and Allergic contact dermatitis to coating or dyes on the Modibodi and not on the Ruby Love.
- We flag Coating degradation and microparticle shedding and Bacterial or fungal growth if improperly stored on the Ruby Love and not on the Modibodi.
- The Modibodi is organic cotton blend with water-resistant coating where the Ruby Love is organic cotton, waterproof backing layer, which is most of the difference in these two grades.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
