At the foot of Mont Blanc, our team of enthusiasts designed waterproof jacket for regular hikes and protecting you from storms in the mountains.

Cut

Fitted cut to fully benefit from the stretch component. The raglan sleeves enable great stretch and frees your movement more when hiking.A warm layer, such as a fleece or light padded jacket, can be worn underneath.

Hood

Adjustable height with an elastic cord and tightening toggle.Integrated semi-rigid visor to provide high level protection.The small detail that makes the difference: a triangular opening on the side of the hood for better visibility to the sides.

Main component

3-layer component with membrane

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.

LAYER DESIGN

3 layer design: The membrane is glued between the outer and inner fabric. We use it for durable and high-performing jackets

COMPONENT WATERPROOFING

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.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.

JACKET WATERPROOFING

We conduct laboratory tests that simulate rainfall scenarios in order to guarantee the jacket's waterproof rating.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.

BREATHABILITY

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 fabricRET ≤ 12: breathable fabricRET ≤ 20: not very breathable fabricThis product was assessed at 6 RET

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. The water-repellent property can be reactivated by putting the jacket in the tumble dryer for 10 minutes on low heat.You can also use the waterproof spray (ref 855490)

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 APPROACH

Because we are aware that we must act to preserve our playground, Quechua is committed to limiting the environmental impact of its products. This jacket is designed to reduce its environmental impact by optimising consumption and weight of the main component. We have reduced the CO2 impact by 31% compared to the previous product.

A lightweight light and breathable jacket that is more respectful of the environment. Its membrane protects you from the rain and wind in the mountains.
