ECOTECH 4 LAYER TECHNOLOGY
Eco Period underwear are as comfortable and functional as your favourite undergarment, but they can do much more: they feature an integrated membrane system in the crotch that draws in your period and leaks into the absorbent core and a final layer that prevents it from leaking through.

The internal skin-touch layer is made of soft, natural wicking fabrics, generally organic cotton or other natural fabrics. The middle layer is made up of specialised organic cotton, bamboo and microfibre that absorb moisture away like a sponge.

The outermost layer is a liquid-impermeable membrane that will not leak fluid, to protect you from leaking, unpleasant stains and sweat marks. In addition, this layer is also breathable, which prevents odours.

The final layer is your base underwear of breathable fabrics, which holds it all together.
