Additional recommended products
Forclaz Rain overtrousers protect the lower half of your body as part of a complete and effective rain protection system for your mountain outings. Care products: spray or liquid water repellent treatment in the washing machine. To renew the fabric's water repellent properties and optimise performance throughout the lifespan of your garment.
Waterproof component
We measure a fabric's resistance to water pressure, expressed as a water column of mm (based on the ISO 811 standard). The higher the water pressure withstood, the more waterproof the fabric. Components scoring 2,000 mm can resist the pressure from 2,000 mm of water (which is equivalent to a rain shower lasting about one hour).
Technologies: this garment has been subjected to a shower test using 100 litres of water/sqm/hour for 3 hours. This test reproduces the conditions of a violent storm in the mountains.
Component breathability
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 evaporates, and the higher the fabric's breathability. For example: RET < 9 = extremely breathable fabric / 9
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.
Water repellent component
A fabric is water repellent when it allows water to slide over its surface without seeping in. This prevents the fabric from swelling, and keeps it lightweight, breathable and warm. The water repellent property is achieved by treating the fabric's exterior. This treatment must be renewed throughout the garment's lifetime (recommended after every three washes).All Quechua waterproof jackets have received a water-repellent treatment.

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?
