Where these two actually differ

- We flag Coating degradation and microparticle shedding and Bacterial or fungal growth if improperly stored on the Ruby Love and not on the Aisle.
- The Aisle is Organic cotton, wood pulp fiber where the Ruby Love is organic cotton, waterproof backing layer, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
