Maintenance

For proper maintenance of O2 - 2.5 layer membranes follow these recommendations: 

 It is important to wash the garment regularly, especially after wearing it in a sweaty, intense aerobic situation or after being exposed to a chemical that may affect its properties.

Wash the garment alone or with other breathable waterproof garments. Do not bring inside out.

Machine wash (never hand wash) in cold water at 30 oC.

Do not use softeners.

5. Use liquid detergent, not to use bleach, avoid powdered detergents.

To increase the duration of the garment and its properties, we recommend the use of nikwax® specific products.

7. Rinse several times (at least two rinse cycles) if necessary, until it doesn´t have any soap smell.
