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.
    9. 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 2000 mm can resist the pressure from 2000 mm of water (which is equivalent to a rain shower lasting about one hour).
    10. Waterproof garment
      NOVADRY® technology: 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. Please visit for more information.
    11. 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 / 920 = little or no breathability.
    12. Garment 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.
    13. Water repellent component
      A fabric is water repellent when it allows water slide over its surface without seeping in. This prevents the fabric from swelling, and keeps it lightweight, breathable and warm. This is achieved through a treatment applied to the fabric's exterior. This treatment must be renewed throughout the garment's lifetime (recommended with each wash). Water repellent treatment products are available in our stores. All Quechua waterproof jackets have received a water-repellent treatment

      Response of the brand
      Hello Nikhilesh Nayak,

      Thanks for your feedback on the Forclaz 400 rain jacket.

      The Forclaz 400 rain jacket is a hard shell or the outer most jacket a user wears when he is on the mountains. It does not provide any warmth, the usage of this jacket is to protect a person from rain and wind, the fabric is 10000 mm waterproof when tested in the water column test generally used to test the waterproofing of a fabric. It is also a stretch fabric which enables more comfort when a user wears it.

      It would be great if you could let me know your usage so that I can suggest you the right product according to your requirement,

    • great looking, leaks during down pours

      I bought this jacket Aug 2014. I have been using it only to walk too and from work which is around 10mins each way. Never really had an issue as i was only out in the rain for a short time. Having said this, I never really used it under heavy sustained rain. in the last couple of weeks i have been taking my daughter to cross country meets, one particular weekend there a was a heavy down pour and thought this was great time to test the jacket out. At the end of the day, items I had in my pocket were wet, my tee shirt covering my shoulders, chest and back were soaking under the jacket. I have always been a big fan of Decathlon and its brand and have bought sports items there for myself and kids since the store came to belfast. i have always found Decathlon products dependable and feel very disappointed by this product.
      great looking jacket and fits well
      leaks during heavy rain

      As a follow up from my review specifying that my old Forclaz 400 waterproof jacket leaked, I got in touch with Decathlon. Customer service, second to none ! My old Forclaz 400 (bought in June 2012) got refunded (a couple of weeks ago, so end of May 2016 !) without questions asked (despite it being purchased in June 2012 !!!!) and after talking at length with a mountaineer specialist I decided to go for the same model again. The New Forclaz 400 model has been improved compared to my 2012 model, and is now much more waterproof, and tested to support sustained heavy rain, to the extent that its waterproof aspect is now very close to matching those dedicated to "serial" hikers / mountaineers. I have discussed it with a few people, hikers and mountaineers, who have all warmly recommended this product to me, including Decathlon's mountain specialist staff. This is what swayed my decision. You look elsewhere, you won't find a product of equal quality at that price. I'd highly recommend this product (although, I haven't yet fully tested it under draconian rainy conditions, but under heavy UK water, it worked !). Note: you can add to this a waterproof spray by Decathlon for £3.99. According to Decathlon's staff, depending on usage, you spray your jacket every 6 months to ensure that its waterproof ability is retained (for instance, if you often wear a backpack) ....
