Trouser hem adjustment

Leg hem tightened with an elastic and toggles to adjust the trousers over the boots. Ankle zip for easy dressing.

Recommended additional product

Care products: waterproof spray or wash-in waterproof liquid. To restore the fabric's water-repellent properties and optimise the garment's performance throughout its lifespan.

Waterproof garment

Technology: this garment has been tested in a shower of 100 L of water/m²/hr for 3 hours. This test reproduces the conditions of a violent storm in the mountains.

Breathable component

To find out whether a fabric is breathable, we test 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 can escape, and the higher the fabric's breathability. For example: RET < 9 = extremely breathable fabric / 920 = little or no breathability.

3-layer, 2-layer or 2.5-layer component

3 layers: the membrane is bonded to an inner and outer layer of the component. This construction prolongs the life of the membrane and enhances the component's performance. 2 layers: the membrane is only bonded to the outer fabric, while the inner protective lining is loose. This construction costs less but is generally more cumbersome. 2.5 layers: the membrane is protected on the inside by a kind of varnish coating rather than an actual layer to make it as lightweight as possible

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 flexible, lightweight and durable, and often more breathable than a coating.

Water-repellent properties of the component (different to waterproofing)

The water repellent property of a fabric its capacity to make water run off its surface without absorbing it. This prevents the fabric from absorbing water and keeps it lightweight, breathable and warm. A fabric is made water repellent by applying a treatment to its outer surface. This treatment must be renewed throughout the lifetime of the garment. We recommended doing this every 3 washes. All the Quechua overtrousers have received a water-repellent treatment.
