Where these two actually differ
- We flag Waterproofing coating composition (non-PFAS factors), Base textile finishing agents (undisclosed), Dye migration and azo dyes and Coating degradation over repeated washing and body heat on the Aisle and not on the Modibodi.
- We flag Water-resistant coating degradation and Microbial growth and odor with improper care on the Modibodi and not on the Aisle.
- The Aisle is Unspecified waterproof/leak-resistant coating on undisclosed base textile where the Modibodi is organic cotton blend with water-resistant coating, 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 Aisle grade, at 35% 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 →
