The small detail that makes the difference: a triangular opening on the side of the hood for better visibility to the sides.

Main component

3-layer component with membrane


The waterproof rating of a product depends on the following two main criteria: its component and its construction.
This product was made with a membrane.
This is a kind of very thin plastic film (polyurethane) that makes the component waterproof while remaining breathable.
It has the advantage of being flexible, lightweight and breathable.


3 layer design: The membrane is glued between the outer and inner fabric. We use it for durable and high-performing jackets


Laboratory tests are conducted to guarantee the waterproof rating of a component. To this end, the resistance of a fabric is measured by the height of a water column in mm that can be supported by the fabric (test based on the JIS 1092 standard). The higher the water pressure, the more waterproof the fabric.
This product's component has a 20,000 mm waterproof rating and can withstand the pressure of a 20,000 mm water column.
This is also equivalent to 20000 Schmerbers.

Water resistance of the jacket

We conduct laboratory tests that simulate rainfall scenarios in order to guarantee the jacket's waterproof rating. This garment has been validated in a shower test under 100 L of water / m² / hour for 3 hours.This test reproduces the average conditions of a mountain storm.


Component breathability is measured by its thermal evaporative resistance (RET).
This is its capacity to let water vapour generated by the body during physical activity escape and therefore avoid water accumulating on the skin.
The lower the RET, the more breathable the fabric.
RET ≤ 6: very breathable fabric
RET ≤ 12: breathable fabric
RET ≤ 20: not very breathable fabric
This product was assessed at 6 RET


A fabric is water repellent when it allows water slide over its surface without seeping in. The fabric does not soak up water and therefore remains lightweight and breathable. The water repellent property is achieved by treating the fabric's exterior. This treatment needs to be renewed during the lifetime of the garment. The water-repellent property can be reactivated by putting the jacket in the tumble dryer for 10 minutes on low heat.
You can also use the waterproof spray (ref 855490)

Always make sure this waterproof jacket is completely dry before storing it.


Our Decathlon Sportslab laboratory, based in Lille, also contributes to the innovation and development of our Quechua products. As well as numerous field tests, we test products in a laboratory according to the desired properties (e.g.: shower test for waterproofness, wind tunnel test for windproof properties, etc.).

Approved By

To meet your requirements, Quechua products are tested in the mountains in conditions you will encounter during your hikes.
Our teams, as well as a tester panel (made up of partners, ambassadors and customers), test products throughout their development until they go to market.
