Specialty waterproofer designed to protect the insulating properties of down-filled gear from wet and damp conditions. Easy to use in the washing machine or by hand, non flammable and PFC free.

Down filled items are used to provide lightweight insulation to keep you warm. The structure of down allows air to be trapped between its filaments and warmed by body heat to provide insulation for the user.

If down gets wet it clumps together. This causes it to lose loft and insulation as it can’t trap air effectively. When wet, down loses all of its insulating properties, as water conducts heat away from the body up to 25 times faster than air. It will also gain weight and its breathability will be significantly reduced; leaving you feeling cold, wet and uncomfortable.

Down filled items are most likely to get sweaty and wet inside when used in damp or wet conditions. Therefore it is important to stop down filled gear from getting wet by applying Durable Water Repellency (DWR). The outer fabric of your down filled item, as well as the down inside, must be maintained to ensure comfort. Through use it will eventually wear off and need to be renewed with Nikwax Down Proof^™.

Nikwax Down Proof™ has been specifically designed and optimized for down filled gear. It 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 fibers allowing moisture vapor to pass through, maintaining breathability and optimizing performance in cold and damp conditions.
