Where these two actually differ
- We flag Undisclosed waterproof coating chemistry, Microplastics and fiber shedding from synthetic blend and Coating adhesion and leaching during use on the Ruby Love and not on the Ruby Love.
- We flag Coating degradation and microparticle shedding and Bacterial or fungal growth if improperly stored on the Ruby Love and not on the Ruby Love.
- The Ruby Love is Nylon/spandex blend with waterproof coating where the Ruby Love is organic cotton, waterproof backing layer, 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 Ruby Love is the one to buy.
- We are less certain about the Ruby Love grade, at 45% confidence against 82%, because it discloses less.
