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 PFAS-free.
Why down items lose their insulating properties when they get wet...
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™.
Down is ideal for very cold and dry conditions…
Down has exceptional insulating properties, trapping air between its filaments to keep you warm. No other product offers so much insulation for so little weight and bulk. It’s ideal for sleeping bags, jackets, gilets and down clothing in general.
Water, whether it is rain or condensation from sweat, compromises the insulating properties of down. If down gets wet it loses all of its insulating capacity and also causes weight gain. This reduces the comfort of the user, causing them to feel cold and wet.
Treating your down with Nikwax Down Proof™ adds Durable Water Repellency (DWR) to both the outer fabric and the down fill. This prevents water absorption whilst maintaining insulation and breathability, keeping you warm, dry and comfortable.
