The topsheet touching your skin right now? Plastic. Polyethylene film — the same material as a grocery bag. It doesn't breathe. It traps heat and moisture all day long.
OCBON replaces it with 100% OCS-certified organic cotton. Breathable, soft, and clean against your skin. Zero rash risk. Nothing synthetic, nothing undisclosed. Women notice the difference within one cycle.
No chlorine bleach. No synthetic fragrance. No PFAS. No plastic film. Just certified organic cotton — verified by the FDA, OCS, and Dermatest Excellent (awarded to fewer than 1 in 5 products tested).
