Organic cotton is a natural fibre grown without pesticides or synthetic fertilisers, using ecological farming practices that protect biodiversity and soil health. Its cultivation respects natural cycles and significantly reduces environmental impact compared to conventional cotton.

Its use in sustainable underwear, base layers and garments worn directly against the skin is highly valued for its natural comfort, breathability and long-lasting quality. In addition, certified organic cotton guarantees full traceability and high environmental and ethical standards throughout the entire production process.

In essence, organic cotton is a clean, soft and responsible fibre, ideal for those seeking comfort, quality and sustainability in their everyday wear.

Organic cotton cultivation

Organic cotton is grown through ecological farming practices that prioritise soil health, biodiversity protection and reduced environmental impact. Unlike conventional cotton, it is cultivated without pesticides or aggressive chemicals, resulting in a purer, safer fibre that is exceptionally gentle on the skin. These responsible methods produce a high-quality natural material ideal for organic cotton underwear and garments worn directly against the skin.

Key characteristics of organic cotton cultivation:

  • Grown from non-GMO seeds, ensuring a natural crop that respects surrounding ecosystems.

  • Fertilised with natural nutrients such as humus or compost, enriching the soil without synthetic substances.

  • Pest control relies on biological methods (ladybirds, bees and ecological traps) avoiding harsh pesticides.

  • Water management is more efficient thanks to increased organic matter in the soil, improving moisture retention and reducing water use.

  • During the textile process, no aggressive chemicals are used; strong bleaches, heavy metals and azo dyes are avoided.

  • The result is a pure, biodegradable and environmentally responsible fibre, ideal for garments in close contact with the skin.

Certifications that guarantee the quality of our garments
  • GOTS (Global Organic Textile Standard): certifies that the entire supply chain — from the fiber to the finished garment — complies with strict environmental and social criteria.
  • OEKO-TEX® STANDARD 100: guarantees that the final product is free from harmful substances and completely safe for direct contact with the skin.

Both certifications ensure that every organic cotton garment by ZD Zero Defects meets the highest standards of purity, sustainability, and well-being.

How to care for organic cotton garments

Organic cotton retains its softness and natural properties with simple care. To ensure its durability and keep your skin protected, follow these recommendations:

  • Machine wash in cold water or at a maximum of 30 °C, using mild detergents and delicate cycles.
  • Avoid dry cleaning, as solvents can alter the natural fiber.
  • Do not use bleach or chemical whiteners, as they damage the color and softness of the fabric.
  • Air dry, away from direct heat sources or intense sunlight.
  • Do not use a tumble dryer or iron, the fabric naturally maintains its shape and softness.

ZD Tip: Wash your garments inside out and, if possible, in a laundry bag. This will help preserve their original appearance and exceptional feel for much longer.
