How to reactivate the waterproof properties of your ski jacket

Water-repellency and waterproof: what's the difference?

Being waterproof is an essential criteria when choosing winter sports equipment:

Let's start at the beginning.

When you kit yourself out for skiing or snowboarding, there are 4 criteria for choosing the jacket and trousers: Warmth,, breathability, other features (such as snow skirt and removable hood) and waterproof.

To find out more, see the guides on how to choose your ski jacket or trousers.

What is the difference between waterproof and water-repellent?

A waterproof membrane prevents water, moisture and air from penetrating a fabric while allowing perspiration to escape.

To preserve this membrane, it’s covered with a water-repellent treatment so the water slides off the surface of the clothing without being absorbed. The water-repellent treatment is visible to the naked eye: the water will form drops. This prevents the ski jacket or trousers from soaking up the water and getting heavy.

It's possible to look after your ski or snowboarding equipment and reactivate their water-repellent properties, and therefore keeping them waterproof, meaning you can enjoy them for longer!

How to use a waterproofing product for fabric?

Waterproofing sprays or ones to reactivate water-repellent properties of fabric can be found easily in store and are specially designed for fabrics and clothing.

It seems stupid, but we’ll say it anyway: to use them, first refer to the instructions provided with the product. Please note: ideally, waterproof your ski wear at least 6 hours before use.


The water-repellent reactivation spray

To use a water-repellent reactivation spray, just spray the product about 20 cm from the ski jacket or trousers applying it evenly and over the entire coverage area.

Then leave your clothing to dry for 10 to 12 hours so the product can really soak into the fabric.


The waterproofing liquid

There are 2 methods of using a waterproofing liquid:

> Hand wash: soak the ski clothing for 15 minutes in 30°C water with the waterproofing liquid.

> Machine wash: pour the waterproofing liquid in the softener compartment and use a 30°C delicates programme.

Please note: do not use washing detergent or softener. If you want to clean your ski clothing, wash it before using the waterproofing treatment.

How to wash your ski wear?

To begin, check that all pockets of your ski jacket or trousers are empty and closed (let them who have never found an old ski pass or lip balm hidden at the bottom of a pocket cast the first stone).

Then, turn your jacket or trousers inside out: turn out sleeves, legs and hoods and close the zips that can be closed.

  • How to wash your ski wear in the washing machine?

    Refer to the garment label
    (oh yes, it’s always best to care for your ski or snowboard wear as instructed by the brand). If you've cut the label out, washing on a 30°C delicate programme followed by a second rinse of the garment should be enough.

    Wash your ski wear separately or with lightly soiled items.

  • Which detergent to use to wash ski wear?

    Use detergent designed for technical clothing.

    If you don’t have any, only use liquid detergent in small quantities.

    Never use washing powder, softener or stain remover.

How to waterproof your ski wear in the tumble dryer?

BE CAREFUL! Your jacket and trousers must be completely dry before being waterproofed in the tumble dryer.

Before putting your ski jacket or trousers in the tumble dryer, check that they are completely dry. If you have washed them beforehand then let them dry in ambient air on a dryer, turning them out at least once.

Once your ski jacket and/or trousers are completely dry, put them in the tumble dryer for 10 minutes on a delicate programme. The heat of the tumble dryer will reactive the water-repellent treatment.

Follow these instructions carefully as waterproof wear dried at too high a heat or for too long can lose all its technical features.

Use the iron to reactivate the waterproof properties of clothing: good or bad idea?

Some waterproof membrane manufacturers also recommend the iron to reactivate the water-repellent properties of your ski jacket or trousers.

At Wedze, we advise against it: it’s an extremely delicate exercise as it's difficult to perfectly control the iron’s heat. An iron that’s too hot can damage the membrane of your ski wear and it may lose all it’s technical features. If you want to try it out after all, never put the iron directly on the garment: protect it using fabric in between and iron it a very low heat with no steam.
