Why Organic Cotton Underwear Is Better...

Most modern clothing from leggings to loungewear is made with synthetic fabrics like Lycra, which often contain forever chemicals (PFAS). These chemicals are used to create stretch, durability, and moisture resistance, but they come at a cost. PFAS are linked to a range of health issues including hormone disruption, skin irritation, and long-term toxic build-up in the body. When these fabrics are worn directly against the most sensitive and absorbent area of a woman’s body without a protective barrier the exposure is immediate and intimate.

In response to this, String Nix was created. A refined, breathable alternative
that prioritises both comfort and conscious design. Made from GOTS certified organic cotton and GRS recycled elastic, our thong offers a protective barrier between your skin and the synthetic world. Soft, supportive, and thoughtfully constructed and protects where it matters most without compromising on fit or style and blends effortlessly under activewear or loungewear.

A Commitment to Certified Quality

At String Nix, we believe that true quality goes beyond aesthetics and functionality. It is about creating products that respect the environment and foster social responsibility. Utilising GOTS Certified organic cotton and GRS recycled elastic in our Nix is proof of our unwavering commitment to these values, ensuring that every garment you purchase from us embodies our dedication to sustainability and excellence.

GOTS is the worldwide leading textile processing standard for organic fibres, including ecological and social criteria. We also use GRS elastic (Global Recycle Standard) which is governed by The Textile Exchange and determines the recycled content of products and ensures that production processes meet stringent environmental and social requirements.
