Good gear isn't cheap, so it's worth looking after. Nikwax has been the trusted name in cleaning and waterproofing for technical clothing, footwear, and equipment since 1977, and for good reason: their wash-in treatments actually restore the breathability and water repellency that regular detergents strip away. Whether it's a down jacket that's gone flat, trail shoes letting water in, or a hardshell that's stopped beading rain, there's a Nikwax product built to bring it back to life. A bit of regular care goes a long way on New Zealand's wetter days, and it's a lot cheaper than replacing gear before its time.
