Organic cotton is not treated with chemicals to prevent shrinkage so after washing they will shrink by up to 5%. Our garments are cut more generously to allow for this shrinkage. Once washed and dried they will have shrunk to the marked size.

Caring for your garment

Always wash garments before use. Our garments made from tough organic cotton, it gets softer with every wash.

Washing your garments

Garments can be machined washed, please care for the environment, wash at 30C. Ensure zips are closed before washing. For best results, wash garments inside out. Wash with ecological or non-biological washing liquids or powders.

Drying and ironing

Line dry your garments for best results and ensure garments are turned inside out when line drying as bright sunlight can fade dark colours. For best results when ironing, iron whilst garment is slightly damp. Placing a cloth over your garment whilst ironing helps reduce sheen.
