Where these two actually differ
- We flag Water-resistant coating degradation and Microbial growth and odor with improper care on the Modibodi and not on the Proof.
- We flag Unspecified waterproof coating chemistry, Coating degradation and microparticle shedding and Skin irritation or sensitization from finish chemicals on the Proof and not on the Modibodi.
- The Modibodi is organic cotton blend with water-resistant coating where the Proof is organic cotton with waterproof coating (unspecified), 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 Modibodi is the one to buy.
- We are less certain about the Proof grade, at 45% confidence against 85%, because it discloses less.
Both products run through the same public rubric: 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 →
