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. This is done by measuring the fabric's resistance to water pressure expressed in terms of the height of a water column in mm (based on the ISO 811 standard). The higher the water pressure, the more waterproof the fabric.
This product's component has a 15,000 mm waterproof rating and can withstand the pressure of a 15,000 mm water column.
This is also equivalent to 15000 Schmerbers.


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 450 L of water/sqm/hour for 4 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


Aside from the breathability of the fabrics used, Quechua develops technical solutions (zips, air holes, mesh, etc.) to improve overall ventilation of all its jackets.
These ventilation systems regulate the temperature inside the garment and help to eliminate the perspiration generated by the body during physical effort.


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)

Product design: our expertise

Our Quechua global design centre is based in Passy, at the foot of Mont-Blanc in Haute Savoie.
This location makes it a real meeting place for our teams (designers, product managers, engineers, etc) and outdoor sports enthusiasts.
A great asset for designing your mountain walking products and providing you with all our expertise.


Because we are aware that we must act to preserve our playground, Quechua is committed to limiting the environmental impact of its products.
Today, this product is not eco-designed, but we work every day to make it more responsible: eco-design, reparability and durability at the heart of our development process.

Product concept & technology

Product Composition

Main fabric 78% Polyamide, 22% Polyester Outer fabric 100% Polyester Coating 100% Polyurethane Inner fabric 100% Polyester Pocket 74% Polyester, 26% Elasthane


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.
It brings together 4 themes, each with their own area and technological tools:
Body shape (3D analysis in particular)
Movement science
Thermal comfort (with its four climatic chambers)
Behavioural and sensory sciences

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.

Maintenance advice

Machine wash - 30° max - normal

Do not bleach

Do not tumble dry

Do not iron

Do not dry-clean
