The material

Cotton absorbs. Bio-Silk™ lets go.

Organic cotton feels natural but holds fluid against your skin. Plastic pads stay dry but trap heat. Bio-Silk™ is our answer to both.

  1. Silky white Bio-Silk fibres drifting through soft green light
    01

    From sugarcane, not oil.

    The topsheet is spun from sugarcane-derived PLA fibre, the same plant-based material used in absorbable sutures. It is smooth by structure: no lint, no pilling, no plastic crinkle.

  2. A VIVILI pad drawing fluid down into its core, rendered in soft teal light
    02

    Dry in under a second.

    Bio-Silk™ is hydrophobic by structure, so fluid passes straight through to the core instead of sitting against your skin. Independently tested 17x drier than organic cotton.

  3. Warm air rising through a VIVILI pad above skin, showing the breathable backing
    03

    Breathes like skin.

    A micro-porous backing lets heat and vapour escape, so you avoid the trapped-heat feeling of plastic-backed pads. No fragrance, no dyes, no chlorine bleaching.

How Bio-Silk works

Your body already knows

Not fragrance to cover odour. A pH your skin already knows.

Healthy intimate skin keeps an acidic pH of around 4.5. Menstrual fluid and lochia are alkaline. Our topsheet is lab-tested at pH 4.5, built into the surface that touches you, with no fragrance.

Our story

Natural, or dry. We refused to choose.

Most period care makes you pick one. Organic cotton feels natural but stays damp. Conventional pads stay dry but are made with petroleum plastics.

So we started with the material.
