We believe it’s important to cut out synthetic fibres wherever possible. 70% of all clothing is still made from synthetic fibres like polyester, acrylic, and nylon, and the vast majority of that is virgin. Use of these materials is particularly prevalent in underwear manufacture, and where some clothing brands have now committed to using natural fibres, there are still very few options when it comes to underwear. Besides the initial impact involved in producing them, synthetic materials shed microplastics when washed, which break down further once they reach landfill or the oceans, eventually entering the food chain.If we’re talking about underwear, then the single most important quality is comfort. In the case of lyocell, it’s even softer than silk, making it incredibly well suited to sitting directly against the skin. It wicks moisture and regulates temperature, and even has natural antibacterial properties.
