- CutThe cut of these over-trousers was designed to be sufficiently wide so it can be worn and taken off easily. In parallel, our model creator, Vanessa, took care of the product’s patronage so that its cut remains feminine despite everything.
- OVER TROUSERS STRUCTURE / 3 LAYERSThese over trousers are made up of 3 layers, the best protection there is on the market: the membrane is glued between the inner and outer component layer (hence it being called 3 layers). The membrane is a kind of very thin polyurethane film that makes the component waterproof while remaining breathable. It is protected by a knit, and has the advantage of being softer, lighter, more durable and often more breathable than a coating.
- WATERPROOFNESS TESTWaterproofing is measured by a fabric’s resistance to water pressure expressed in mm of water column (JIS 1092 standard) The higher the pressure, the more waterproof the fabric. The component of this product has a waterproof rating of 15,000 mm, i.e. it can withstand the pressure exerted by a 15,000 mm column of water. This is also equivalent to 15 000 Schmerbers.
- BREATHABILITY TESTComponent breathability is measured by its thermal evaporative resistance (RET). This is its capacity to let water vapour generated by the body during physical activity escape and therefore avoid water accumulating on the skin. The lower the RET, the more breathable the fabric. RET ≤ 6: very breathable fabric RET ≤ 12: breathable fabric RET ≤ 20: fabric with relatively little breathability Our product has an RET of 8.
- Product design: our expertiseOur Quechua global design centre is based in Passy, at the foot of Mont-Blanc in Haute Savoie. This location makes it a real meeting place for our teams (designers, product managers, engineers, etc) and outdoor sports enthusiasts. A great asset for designing your mountain walking products and providing you with all our expertise.
- HOW TO RESTORE THE WATER-REPELLENT PROPERTY OF MY OVER-TROUSERS?The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it. In this way, the over trousers do not soak up water and stay lightweight and breathable. The fabric is made water-repellent by treating its outer surface, however this property may deteriorate with use. All the steps to restore the water-repellent properties are below: https://conseilsport.decathlon.fr/conseils/comment-reactiver-la-deperlance-de-sa-veste-tp_22965
