Ever gone out wearing your favourite down jacket, got caught in the rain and ended up feeling wet and cold? Maybe you thought your jacket was water-repellent or perhaps you were hoping for good weather. Whatever the reason, no one likes to feel cold, wet and uncomfortable. There is a solution: Nikwax Down Proof™.
My experience of Down Proof is not favourable unfortunately, I used it exactly as described on a lightweight down sleeping bag. The result was clumped feathers which I then had to get professionally cleaned for £45.
