TotsBots builds its nappy from a bamboo viscose inner and a recycled-polyester waterproof outer, so by the Throne Standard TotsBots contains no natural plant fibre and does not pass. TotsBots markets its bamboo as natural, but the flag here is that bamboo fabric is bamboo viscose, a chemically regenerated semi-synthetic fibre. TotsBots is made in Glasgow and is fully OEKO-TEX 100 certified, which means TotsBots is tested for harmful substances but is not certified as a natural or plant-fibre product.
