How to restore the water-repellent properties?

Care products: spray or wash-in waterproof product to restore the water repellent property of the fabric and optimise the performance of your garment throughout its lifetime.
All the details to restore the water repellent properties:

Jacket construction with membrane

- 3 layers: The membrane is glued between the outer fabric and the inner fabric. Used for resistant and high-performance jackets
- 2.5 layers: The membrane is glued under the outer fabric and protected by a thin film on the inside. Used for lightweight jackets.
- 2 layers: the membrane is glued only to the outer fabric; the inner protective lining is free. Used for comfortable jackets


We measure a fabric's resistance to a column of water in mm (based on the ISO 811 standard). The higher the pressure, the more waterproof the fabric. A component with a waterproof rating of 2,000 mm is able to resist the pressure exerted by 2,000 mm of water (roughly equivalent to a 2 hour rain shower).


This garment has been shower-tested using 60 litres of water/ m² /hour for 3 hours. This test reproduces the conditions of a violent storm in the mountains.


To find out whether a fabric is breathable, we test its evaporative resistance or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more water vapour generated by physical activity can escape and the higher the fabric's breathability. For example: RET < 9 = extremely breathable fabric / 920 = little or no breathability.


The water repellent property of a fabric is its ability to make water run off its surface without absorbing it. In this way, the fabric does not get waterlogged and remains light, breathable and warm. The water repellent property is obtained by applying a treatment to the outer surface of the fabric. This treatment needs to be renewed during the life of the garment (we recommend every 3 washes). All Quechua over-trousers have a water repellent treatment.
