    7. Main component
      2-layer coated fabric.
    8. Technical linings
      Micro-fleece inside the waist and on the seat for comfort/nylon around the knees for ease of movement and durability/mesh on the thighs for breathability.
    9. Recommended additional product
      Care products: waterproofing spray or liquid in the machine To renew the fabric's water repellent properties and optimise performance throughout the lifespan of your garment.
    10. Component waterproofing
      We test a fabric's resistance to water pressure by measuring the height of a column of water supported by the fabric in mm (test based on the ISO 811 standard). The better the fabric resists pressure, the more waterproof it is. 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 hour).
    11. Waterproofing of the garment
      This garment was approved in a shower test in 100 L of water/m²/hour for 3 hours. 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 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 advantage of being more supple, lightweight, durable and often more breathable than the coating.
    13. Component breathability
      To find out whether a fabric is breathable, we measure 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 is evaporated, 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 = fabric is not breathable or has low 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 its hiking jackets and overtrousers. 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 component
      A fabric is water repellent when it allows water to slide over its surface without seeping in. This prevents the fabric from soaking up water and keeps it lightweight and breathable. A fabric becomes water repellent by applying a treatment to its outer surface. This treatment must be renewed throughout the garment's lifetime (recommended after every three washes). All Quechua overtrousers benefit from a waterproofing treatment.

      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.
    • NOT WATERPROOF..

      I'm typing this while I'm still wet from the VERY FIRST TIME of using these in rain for MERELY 20-25 MINUTES on a scooter on open roads at 2.30 am.
      Outer material is water repellent but these leak very badly from the Crotch and Pocket (both sides) area. It wasn't even raining too heavily.
      I've always been a fan of decathlon products and recommend to many (last year's hiking jacket is still holding up well) but this time I'm Highly Dissappointed.
      Response of the brand
      Hello Mr Ovais,

      Thank you for your feedback on the Forclaz 100 Waterproof Hiking Trouser. We regret the unpleasant experience you have had with the trouser. This over trouser is designed to protect you from rain, wind and snow while you are hiking in the mountain, but I am sorry to inform you that this is not suitable for riding a bike because hiking requires a fabric which stops water but allows breathability to stop the user from sweating. When it is used for bike riding, the water strikes the fabric with higher pressure and enters through the breathability pores which is not the case when you are hiking. However, If you are not satisfied with the product you can visit any of our stores for an exchange or refund.

      I remain available if you need any further help.

      Sportingly,

      Varun Nair
