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 Cora.
- We flag Undisclosed core and backing materials and Super-absorbent polymer (SAP) microparticulate or leachate on the Cora and not on the Aisle.
- The Aisle is Organic cotton, wood pulp fiber where the Cora is 100% organic cotton topsheet, which is most of the difference in these two grades.
- The gap is 30 points, wide enough that this is not a close call, and the Aisle is the one to buy.
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 →
