Important information about care and maintenance: 1. Machine wash in cold water without other garments which might scratch it (like jeans). 2. Do not use softener. 3. Rinse several times if necessary: although it might seem strange, the jacket must NOT smell soapy when you take it out.

Recommended products for washing, maintenance and care of waterproof garments.

Please avoid deodorants, make-up or sun creams in direct contact with the membrane as they can pollute your jacket.
