  8. High-tech lining
    Micro-fleece at the waistband and seat for comfort. Nylon around the knees for freedom of movement and durability. Mesh on the thighs for breathability.
  9. Recommended additional product
    Care products: waterproof spray or wash-in waterproof liquid to restore the fabric's water repellent properties and optimise the garment’s performance throughout its lifespan.
  10. Component waterproofing
    We measure a 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 pressure, the more the fabric is waterproof. Components with a 2000 mm rating can withstand the pressure of a 2000 mm column of water (which is equivalent to a rain shower lasting two hours).
  11. Waterproofing of the garment
    This garment was passed following a 3-hour shower test under 100 L of water/m²/hr. This test reproduces the conditions of a violent storm in the mountains.
  12. Component with membrane or coating
    The coating is like a layer of "paint" applied to 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 advantage of being more flexible, lightweight, durable and often more breathable than a coating.
  13. Component breathability
    To assess the breathability of the fabric, the evaporative resistance, RET (test based on the ISO 11092 standard), is measured. The lower the fabric's resistance, the more water vapour generated by physical activity can escape, and the higher the fabric's breathability. For example: RET < 9 = extremely breathable fabric / 9 < RET < 12 = very breathable fabric / 12 < RET < 20 = breathable fabric / RET > 20 = little or no breathability.
  14. Breathability of the garment
    In addition to breathable fabrics, Quechua develops high-tech solutions (zips, ventilation, mesh, etc.) to improve the overall ventilation of all its hiking jackets and over-trousers. 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.
  15. Water repellent property of the component
    A fabric's water repellent property is its capacity to make water run off its surface without absorbing it. This prevents the fabric from absorbing water and keeps it lightweight, breathable and warm. A fabric is made water repellent by applying a treatment to its outer surface. This treatment must be renewed throughout the garment's lifetime (with every 3 washes). All the Quechua over-trousers have a water repellent treatment.
  16. A score for comparing products' environmental impact
    The product's environmental impact is calculated over its entire life cycle using different indicators. An overall rating of A to E is provided to help you easily identify the more eco-friendly products by comparing products of the same type with each other (T-shirts, trousers, backpacks, etc.) Decathlon is committed to displaying the environmental information of its products.

  • Great Value

    Warby (United Kingdom)
    Used for 7 to 12 months
    I have a few pairs if these,,, great for everything,, I use on my motorbike for enduro as they fit over my knee pods.. totally waterproof.
  • Use them for skiing

    These trousers are waterproof, breathable, they are listed for hiking, but I bought them for skiing for my teenage sons, my children quickly get hot in normal material, as the sun can be very hot before Christmas and from February on up in the mountains. These trousers are light weight, the material has got a fantastic touch, colour and they have outside zippers up to the side pockets which makes it easy to put them over ski boots, they wear EU size 46 and 48, 46 is L-XL, 48 is XL and they fit perfectly. The only thing is, inside at the bottom of the trousers are no cuffs, it's not possible because of the zip. If you would do sledding in these trousers, snow would come up along your boots, as you have your feet always next to your sledge on the ground. The boys will also wear on those freezing days one of Decathlon's long johns under it.
  • Pretty usable, but odd dimensions.

    I use these pants mainly for sailing.

    On the upside. It is pretty sturdy and it slips on and off pretty easily thanks to the side-zippers. The waist and suspenders are well adjustable. The sturdy central closure keeps it all in place. So far during some extended rain they have kept me dry. They also seemed to breath. The pants are intricately lined, the thighs by webbing for ventilation, and the bottom seems intended to keep extra warmth.

    On the downside. The lower ends of the legs are ridiculously wide. I am really wondering why, because for putting on the pants they are pointless as they have the side-zippers. Maybe it is because of the other shortcomings. They are very short too! And then they get pulled up a lot when bending my legs, probably because of all the lining, and maybe the fabric not being very flexible. I also wondered whether it would be better with less lining as that makes the pants pretty heavy while one can wear some clothing of own choice underneath. Then there are the typical Decathlon not-so-clever-clever-details like loops inside the legs' lower ends. No bother, but they could just be left out.
