Waterproof fabric
We measure a fabric's resistance to water pressure, expressed as a water column in mm (based on the ISO 811 standard). The higher the water pressure, the more waterproof the fabric. A fabric with a 2000 mm waterproof rating can withstand the pressure of 2000 mm water (corresponding to about an hour of rain).
Garment waterproofing
Technology: this garment has been shower-tested using 100 litres of water/sqm/hour for 3 hours. This test reproduces the conditions of a violent storm in the mountains.the inner layer is a coating rather than a genuine layer
Fabric breathability
In addition to breathable fabrics, Quechua develops technical solutions (zips, ventilation, mesh, etc.) to improve the overall ventilation of its trekking jackets and overtrousers (Forclaz, Bionnassay and Helium lines). These ventilation systems allow you to regulate the temperature inside the garment and also to facilitate the transfer of perspiration generated by the body during physical effort.
Fabric with coating or a membrane
Coating: like a layer of "paint" applied on the underside of the fabric to make it waterproof while remaining breathable. It is often less costly than a membrane, and requires a lining for protection.The membrane: is like a very fine plastic film (polyurethane) making the component waterproof while remaining breathable. It has the edge, being more supple, lightweight, durable and often more breathable than coating.
3-, 2- or 2.5-layer fabric
"3 layers": the membrane is bonded to an inner and outer layer of the component. This construction helps the membrane last longer and boosts the component's performance. "2 layers": the membrane is only bonded to the outer layer, the inner protective lining is "free". This construction costs less but is generally more cumbersome. "2.5 layers": the membrane has inner protection with a kind of varnish coating rather than an actual layer to make it as lightweight as possible.
Water repellent fabric
A fabric is water repellent when it allows water to slide over its surface without seeping in. This prevents the fabric from becoming saturated, and keeps it lightweight, breathable and warm. The fabric is made water repellent by treating its outer surface. This treatment must be renewed throughout the garment's lifetime (recommended after every three washes). All the Quechua waterproof jackets have received a water-repellent treatment.
Additional recommended products
Forclaz Rain overtrousers also protect the lower half of your body, forming a complete and effective rain protection system for your mountain excursions. Care products: spray or liquid water repellent treatment in the washing machine. Helps renew fabric's water-repellent properties and optimise your garment performance throughout its life.

Used for 2 to 8 weeks
Snow wind rain....does what it says in the description....worn on winter wild camp in Snowdonia perfect!
bad service and product
Used for 2 to 8 weeks
I bought this jacket in May in Edinburgh, after a couple of weeks of use : water was seeping through the collar and the side pockets. Went to the shop for an exchange : they didn't have the right size and the model wasn't produced anymore.. The shop in Glasgow did but refused to send it through. Didn't have time to go there to do it myself. Was advised to reproof it : after a month use, a brand new jacket!
Very disappointed with the product and the service. The quality seems to have gone down since decathlon started. I'm French and have often bought watersports equipments of very good quality in the past 15 years from decathlon.
comfortable jacket
not waterproof or water repellent
Response of the brand
Very sorry to hear about your experience in our stores. It is not acceptable and have passed it on to the store managers in Edinburgh and Glasgow. You can still return your jacket if you still have it and we can replace it for the new model if that works for you?
