Standard cut. Can be worn over trousers, leggings or shorts. Caution: no hems possible due to the zips on the side of the legs
3-layer component with membrane
The waterproof rating of a product depends on the following two main criteria: its component and its construction.
This product was made with a membrane.
This is a kind of very thin plastic film (polyurethane) that makes the component waterproof while remaining breathable.
It has the advantage of being flexible, lightweight and breathable.
3 layer design: The membrane is glued between the outer and inner fabric. We use it for durable and high performance over-trousers
WATERPROOF FEATURE OF THE COMPONENT
Laboratory tests are conducted to guarantee the waterproof rating of a component. This is done by measuring the 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 water pressure, the more waterproof the fabric.
A component with a waterproof rating of 10,000 mm can therefore withstand the pressure exerted by a 10,000 mm column of water. This is also equivalent to 10,000 Schmerbers.
WATERPROOFING OF THE OVER-TROUSERS
To check the waterproofing of the overtrousers, we carry out laboratory tests to simulate rainy weather.
This garment has been validated in a shower test under 100 L/sqm/hr of water for 3 hours. This test reproduces the average conditions of a mountain storm.
HOW TO RESTORE THE WATER-REPELLENT PROPERTIES
A fabric is water repellent when it allows water slide over its surface without seeping in. The fabric does not soak up water and therefore remains lightweight and breathable. The water repellent property is achieved by treating the fabric's exterior. This treatment needs to be renewed during the lifetime of the garment. Water-repellent properties can be reactivated by tumble drying the trousers for 10 minutes on low temperature or by using a reactivating spray.( Ref: 8551983)
Component 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: not very breathable fabric

Product design: our expertise
Our 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.
OUR ENVIRONMENTAL POLICY
Because we are aware that we must act to preserve our playground, Quechua is committed to limiting the environmental impact of its products.
Today, this product is not eco-designed, but we work every day to make it more responsible: eco-design, repairability and sustainability are at the heart of our developments.
