Stormproof is a high tech reproofing agent for use on all fabric types and leather. Perfect for breathable fabrics, Gore-Tex® and regular rip stop nylon. It even works well on fleeces and wool clothing.

A durable water repellent (DWR) coating keeps your garment working to the best of its ability, but the coatings do not last forever, and heavy use can make them wear off quickly.

When the DWR has worn off, your jacket will begin to absorb water and feel wet. This is called “wetting out”. It does not mean your waterproof jacket leaks, but it may feel that way while you’re wearing it. The inside of your jacket might feel cold or damp and clammy without a DWR to prevent the outside fabric from absorbing water. At this point, the breathability of your jacket may well be compromised and you might feel condensed moisture on the inside of the jacket. If your rainwear “wets out” on a trip may be unpleasant, but it doesn’t mean you need to buy a whole new jacket.

StormProof DWR can be easily reapplied and the garment will be transformed to its original performance once again. Wash it and rinse in clean water then apply StormProof and leave to air dry. Gentle warming or tumble drying will improve repellency.
