LAYER DESIGN
3 layer design: The membrane is glued between the outer and inner fabric. We use it for durable and high performance over-trousers
WATERPROOFING OF THE OVER-TROUSERS
We conduct laboratory tests that simulate rainfall scenarios in order to guarantee the jacket's waterproof rating.
This garment has been inspected in a shower test under 18 cm rain for 2 hours. This test reproduces the average conditions of a mountain storm.
WHERE DO OUR TROUSERS COME FROM?
Designed at our international design centre at the foot of Mont Blanc in France, these overtrousers are then manufactured by our suppliers in Bangladesh.
We collaborate closely with these partners who have real expertise in the manufacture of over trousers.
Thanks to this relationship of trust with our industrial partners, we can create high-quality technical products.
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.
COMPONENT BREATHABILITY
The JIS L 1099 B1 test measures the water vapour that passes through the fabric in 24h, in grams per sqm. The higher this value is, the more breathable the fabric. A performance rating of 10,000 g/m²/24 hr, with breathability, makes it ideal for hiking.
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.
Fit
Standard cut. Can be worn over trousers, leggings or shorts. Caution: no hems possible due to the zips on the side of the legs
Main component
3-layer component with membrane
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)
WATERPROOF FEATURE OF THE COMPONENT
Laboratory tests are conducted to guarantee the waterproof rating of a component. To this end, the resistance of a fabric is measured by the height of a water column in mm that can be supported by the fabric (test based on the JIS 1092 standard).
The higher the water pressure, the more waterproof the fabric.
This product's component has a 15,000 mm waterproof rating and can withstand the pressure of a 15,000 mm water column. This is also equivalent to 15000 Schmerbers.
