How Nikwax Down Proof™ protects:

Nikwax Down Proof™ adds Durable Water Repellency (DWR), which protects against rain and condensation, improving the natural insulating properties of down.

Nikwax Down Proof™ prolongs the effective life of your down gear. It leaves a flexible water repellent treatment on individual down filaments and fabric fibres allowing moisture vapour to pass through, maintaining breathability and optimising performance in cold and damp conditions.

Nikwax Down Proof™ is quick to apply in a washing machine and ensures that the treatment goes right through the item, treating both the outer fabric and the down fill. The DWR of Nikwax Down Proof™ develops on air drying. However, tumble drying is recommended to ensure that the down is dried thoroughly and as quickly as possible. Leaving down wet or damp can ruin it completely.

Uses per bottle:
