Saalt Leakproof Period Cotton Brief, Heavy / S / Pink Dawn vs Rubylove First Period Kit +teen Period Underwear: which is safer?

Where these two actually differ

• We flag Unspecified waterproof coating chemistry and Skin irritation or sensitization from finish chemicals on the Proof and not on the Ruby Love.
• We flag Bacterial or fungal growth if improperly stored on the Ruby Love and not on the Proof.
• Both carry a flag for Coating degradation and microparticle shedding, so neither choice avoids it.
• The Proof is organic cotton with waterproof coating (unspecified) 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 Proof grade, at 45% confidence against 82%, because it discloses less.
