How to Wash and Reproof Waterproof GearUpdated 4 hours ago

To preserve the performance and technical lifespan of your waterproof gear, only wash it when necessary, and always handle it with care.

Machine washing

• Preparation: Zip up all pockets and main zippers, fasten Velcro cuffs, and loosen drawstrings before placing the garment in the machine.
• Temperature: Wash at 30°C maximum on a synthetic or outdoor cycle.
• Specialised cleaner: Use a dedicated technical detergent designed for waterproof membranes to protect breathability. We recommend Nikwax Tech Wash® (available in 300 ml or 1 L).
• No standard detergents: Avoid everyday household detergents, as they often contain optical brighteners, bleaching agents, or perfumes that clog the membrane pores.
• Never use fabric softener: Softeners leave a residue that degrades both breathability and the durable water-repellent (DWR) finish.
• Gentle spin: Select a low spin speed capped at 400 rpm to avoid stressing the taped seams.

Drying

• Air-dry naturally: Hang your garment on a wide hanger and allow it to dry naturally in a well-ventilated area.
• Keep away from heat: Avoid direct radiators, heaters, and direct sunlight.
• Do not tumble dry unless specifically indicated on the care label.

Reviving the water repellency (DWR)

Over time, dirt, friction, and moisture break down the outer water-repellent finish, causing water to pool rather than bead up. When this happens:

Apply a technical reproofing spray or wash-in treatment (such as Nikwax TX.Direct®) to restore surface water beading without compromising the membrane’s breathability.
