Where these two actually differ
- We flag Waterproof coating leaching (fluoropolymer or polyurethane-based), Coating microparticle shedding during washing and Inadequate rinsing of residual coating chemicals on the Icon Underwear 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 Icon Underwear.
- The Icon Underwear is Fabric with moisture-wicking and waterproof coating where the Ruby Love is organic cotton, waterproof backing layer, which is most of the difference in these two grades.
- The gap is 75 points, wide enough that this is not a close call, and the Ruby Love is the one to buy.
- We are less certain about the Icon Underwear grade, at 35% confidence against 82%, because it discloses less.
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 →
