I recommend

Plain black impermeable and poorly breathable pants. I don't feel that they are breathable (when using them on a scooter), but they isolate perfectly from the wind - on colder days. I bought it mainly against precipitation, but I like to use it on colder days. Zippers at the bottom make it easy to put your foot in place, even with the shoe on. I recommend They could have reflectors or other color variants

Additional Product Information


Main fabric: 100.0% Polyester ; Coating: 100.0% Polyurethane

Waterproofing of the garment

This garment has been validated in a shower test under 60 litres of water/sqm/hour for 2 hours. This test reproduces the average conditions of a rain shower. The fabric of these overtrousers has water-repellent properties: it lets water slide over its surface without seeping in. This prevents the fabric from soaking up water and keeps it lightweight and breathable. The water repellent property is achieved by treating the fabric's exterior. What's more, all the seams are taped.

How to ensure your overtrousers stay waterproof over time

In order to maintain good waterproofing over time, the fabric's water-repellent properties must be restored regularly. We recommend doing this every three washes or after a dozen uses in the rain. The waterproof property is easily reactivated by warming the fabric: either in your tumble dryer or with a hair dryer, for example, over a relatively short period. If you are washing it, it must be thoroughly rinsed.

Waterproof rating expressed in mm or schmerber

We measure a 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 2,000 mm can therefore withstand the pressure exerted by a 2,000 mm water column.

Component breathability

To find out whether a fabric is breathable, we measure its thermal evaporative resistance coefficient (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. - RET < 9 = extremely breathable fabric - 9 < RET < 12 = very breathable fabric - 12 < RET < 20 = breathable fabric - RET > 20 = little or no breathability

How to choose your waterproof overtrousers based on your outings and level of exertion?

During a sporting activity, you perspires to varying degrees, depending on the intensity or length of the effort. If the fabric's breathability is not suited to the type of activity/exercise, your perspiration will condense inside the jacket. You feel damp inside: this isn't rain getting through, but condensation from sweat. You therefore need to choose over-trousers in line with your activity type. This product is designed for 2-hour hikes at no more than 5km/h.


Our hiking overtrousers are guaranteed for 2 years. Our commitment? To offer you long-lasting products that you can use on all your country hikes and walks. Because the products we love the most are those that have a story behind them... and plenty of life in them yet!

Product testing

It’s in France, at the foot of Mont Blanc, that our design team conceives, creates and designs the Quechua products. We test them in the laboratory and in the field with other hikers to make sure that they are comfortable and waterproof. Whether it is in the forest, on the coast or in the countryside in fine or rainy weather, we cover as many different trails as possible. This creates plenty of opportunities for discussions to get your feedback which is used to plan our future products.

Storage instructions

It is important to always make sure that the trousers completely dry before putting them away.
