  • Silk is halal for women. For men there is a difference of opinion regarding this. The hanafi Madhab for example permits clothing in which there is less than 50% silk. This is the case with our cotton-silk products. In some schools certain exceptional circumstances where there is shar’i evidence to support this. People who are sick may also be permitted to wear silk to relieve their suffering, as Anas reported that the Prophet allowed ‘Abd al-Rahmaan ibn ‘Awf and Ibn al-Zubayr to wear silk because of a skin irritation that they suffered from. These scholars also allowed men to wear garments containing four fingers’ width of silk. For Ynside products combining organic cotton and silk, only the front interior is made out of silk and less than four fingers wide. Source.

Silk is a very joyful, strong, but delicate fabric. To prolong its beauty, handle with care like you would with your hair.

  1. Seek out detergents specifically created for silk or delicate garments like wool. Organic and biodegradable. Nothing at home? You could use a small amount of a mild hair shampoo.
  2. 30°C max. Use a programme for washing delicate articles or wool/silk. Wash at a temperature range from cold to 30° degrees Celsius (86° Fahrenheit).
  3. Do not tumble dry Ynside underwear. Best solution is to line dry and to not expose the product to direct sunlight. UV light is damaging to silk.
  4. It is better to not iron silk. If whished, be sure that the fabric must always be damp when ironing at the lowest temperature.
  5. *Hint: using natural vinegar as a ‘fabric softener’ will ensure your underwear keeps its color better. It also helps to neutralize detergents and makes your silk shine bright. In conclusion, vinegar is a natural way to clean your washing machine.
