Where these two actually differ
- We flag Azo dyes and synthetic dyes and Allergic contact dermatitis from dyes or finishes on the Aisle and not on the Dear Kate.
- We flag Fluorochemical/PFAS in waterproof coating, Degradation of waterproof coating over time, Residual dyes and processing chemicals in nylon and Contact dermatitis or allergic reaction on the Dear Kate and not on the Aisle.
- The Aisle is Organic cotton, wood pulp fiber where the Dear Kate is Nylon/spandex blend with waterproof treatment (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 Aisle is the one to buy.
- We are less certain about the Dear Kate grade, at 42% confidence against 72%, 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 →
