Your NAT’V pieces are made with luxe, sustainable fabrics — from Organic Cotton to Lenzing Modal and Recycled Nylon. To keep them soft, supportive, and planet-friendly for longer, show them a little care:

1. 
   Wash gently — Cold or warm machine wash (up to 40°C) on a delicate cycle with similar colours. This cleans effectively and protects your fabrics.
   
2. 
   Keep it hygienic — Everyday washes at 30–40°C with good detergent are enough to kill bacteria. If you want extra freshness (like after being unwell), you can do an occasional hotter wash — just don’t make it a habit, as high heat breaks down elastic and fibres.
   
3. 
   Use kinder detergent — Mild, eco-friendly detergent only. No bleach, no softeners, no harsh chemicals.
   
4. 
   Skip the dryer — Line dry in the shade. Heat from dryers or direct sun weakens elastic and damages fabrics.
   
5. 
   No ironing needed — Our fabrics are designed to stay smooth and comfy without it.

✨ Treat your NAT’Vs with love, and they’ll love you longer.
