CARING FOR WATERPROOF GEAR

Keep your wet-weather kit working well

Telltale signs

Modern garments generally have an inner waterproof membrane and an outer material that’s treated with a Durable Water Repellent (DWR) finish. This causes liquid on the surface to ‘bead’ and roll off, to prevent the material becoming saturated, while still allowing the fabric to wick sweat away. When moisture starts getting trapped inside and the outer fabric starts to ‘wet out’, it’s time to act.

Everyday care

After a wet ride, empty any pockets and close zips and openings, then hang to air-dry. When dry, use a soft-bristled brush to remove excess dirt. Waterproofs rarely look shop-fresh again but making sure they’re clear of grime keeps them breathable and lets the DWR coating work. Storing them flat reduces friction on the fabric, which can damage the coating.

Cleaning

When the performance of the DWR coating begins to degrade, wash with a technical cleaning product, by hand or in a machine (cool wash/minimum spin cycles). Unlike regular detergent, which will strip the DWR and clog the fibres, a technical wash will restore the breathability and water-repellence of the garment. The DWR finish can then be reactivated by applying gentle heat, by hanging the item above a radiator or using the cool setting on a tumble dryer.

Reproofing and repairing

When cleaning isn’t enough to stop the fabric wetting out, it’s time to apply a new DWR treatment. This can be done at home, either by using a wash-in proofer in a washing machine or by spraying the coating directly on and using gentle heat to activate it. Damage to taped seams and small tears can also be mended at home, with waterproof repair kits. Companies such as Alpkit and Rapha now offer repair services, too.
