Across our five-brand sample, the product with the lowest per-unit weight demonstrated the highest total absorption capacity. This counterintuitive finding — less material, more performance — is explained by superior SAP selection and core architecture design rather than material quantity.
Weight vs Performance Paradox
The lightest diaper had the highest total absorption capacity.
Key Result
LIGHTEST = BEST
