Nikwax - The easy waterproof test

A good test on any type of waterproof gear is to see if water beads on the surface to form fine droplets. If droplets bead, this is a sign the gear is waterproofed and is repelling water. If gear doesn’t bead but ‘wets out’, you will see darker patches where water is being absorbed through the surface. This is a sign the gear is not performing and requires the Nikwax waterproofing treatment.
