Our team of passionate mountain trekkers has designed these over-trousers so you can go trekking in wet weather while being completely protected. Waterproof over-trousers using the combination of a lightweight, breathable fabric and a sturdy fabric to help protect you from the elements.
Use of a sturdy fabric (147 g/sqm, 70 Denier) on the areas to be protected.
Combination of 2 fabrics resistant to 20,000 mm water pressure before washing.
The double-slider side zip helps regulate body temperature.
RET < 8 for the lightest fabric, RET < 12 for the most resistant fabric
Full-length side openings with waterproof double-slider zips
The hybrid construction reduces the weight to 380 g in size M.
Freedom of movement
Preformed knees. Half-elasticated waist adjustable by cord and toggle.

Combination of a durable and protective fabric (147 g/sqm; 70 Denier) on areas to be protected from rubbing (knees, lower leg, buttocks) and a light and breathable fabric (109 g/sqm; 20 Denier) elsewhere.
Using a waterproof zip with a double slider lets you both regulate your body temperature and easily put on the over-trousers without having to remove your boots. Press-studs at the waist and ankles.
Bottom of trouser leg has an elastic strip with silicone inside to improve grip on the boot. Lower leg hook to attach to the laces of the boot to prevent the over-trousers from riding up while walking.
The resistance of a fabric to water pressure is expressed in terms of the height in mm of a water column that can be supported by the fabric (test based on the ISO 811 standard). The higher the pressure, the more waterproof the fabric. Here are the waterproof values of the Trek 500 over-trousers: 25,000 mm before washing for the lightest fabric (11,000 mm after 5 washes) 20,000 mm before washing for the strongest fabric (17,000 mm after 5 washes)
The water resistance of the over-trousers was tested under rainfall of 450 litres of water/m²/hour for 4 hours. This test reproduces the conditions of a thunderstorm in the mountains.
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 the water vapour generated by physical activity can escape, and the higher the fabric's breathability.It is considered that if: * RET < 9 = very breathable fabric * 9 < RET < 12 = breathable fabric Here are the breathability values of the Trek 700 over-trousers: RET < 8 for the lightest fabric RET < 12 for the most resistant fabric
The water repellent property of a fabric is its capacity to make water run off its surface without absorbing it. This prevents the fabric from soaking up water, and keeps it lightweight and breathable. The fabric is made water repellent by treating its outer surface, however this property may deteriorate with use. In order to reactivate it, follow the guide: https://www.quechua.co.uk/advice/how-do-you-restore-water-repellent-properties-your-jacket-a_86425
The product's environmental impact is calculated over its entire life cycle using various indicators. An overall score from A to E is given to help you easily identify the most eco-friendly products by comparing products of the same type (T-shirts, trousers, rucksacks, etc.) with each other. Decathlon is committed to displaying the environmental information of its products. For more information: http://sustainability.decathlon.com/
