WATERPROOF TECHNOLOGY: DWR

Technology Detail Hero Image

DURABLE WATER REPELLENT TECHNOLOGY

Durable Water Repellent (DWR) is a special waterproof finish, applied to the face fabric of our waterproof jackets and winter trousers to maintain a high level of waterproofness and breathability.

Without DWR the face fabric would ‘wet out’ (become waterlogged) meaning that perspiration would be unable to escape from the body because it would be stopped by the wet layer.

The perspiration would then cool and condense on the inside of the jacket making you wet and ultimately, colder. This is of course not ideal for vigorous outdoor activities such as climbing which is why Berghaus have chosen this coating to use for their men and women’s waterproof jackets and clothing.

Caring for your waterproof

Whilst DWR is not a permanent feature of the fabric, exposure to the elements, washing the garment and regular wear can strip the DWR from the fabric. It is essential that if your clothing has a DWR finish it is well-maintained to ensure your clothing performs at its best. This might include a washing routine that brings life back to the structure of the fabric and seasonal re-proofing to ensure that your waterproof jacket continues to keep you dry even in the harshest conditions.

You can find out how to prolong the life of your waterproof jacket and how to keep it clean using our guide to washing a waterproof jacket.

All waterproof jackets need to be reproofed from time to time as general wear can reduce a product’s effectiveness. Luckily it’s simple to do with our handy guide to reproofing using Nikwax Waterproof Aftercare.
