Waterproof overpants using the combination of a lightweight, breathable fabric and a sturdy fabric to help protect you from the elements.
Our team of passionate mountain trekkers has designed these overpants so you can go backpacking in wet weather while being completely protected.
Hybrid construction
Combination of a durable and protective fabric (5.2 oz/m2; 70 Denier) on areas to be protected from rubbing (knees, lower leg, buttocks) and a light and breathable fabric (3.8 oz/m2; 20 Denier) elsewhere.
Side zippers
Using a waterproof zipper with a double slider lets you both regulate your body temperature and easily put on the overpants without having to remove your boots.
Press-studs at the waist and ankles.
Protection
Bottom of pant 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 overpants from riding up while walking.
Water-resistance of the fabric
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 overpants:
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)
Water-resistance of the overpants
The water-resistance of the overpants was tested under rainfall of 119 gallons of water/mΒ²/hour for 4 hours. This test reproduces the conditions of a thunderstorm in the mountains.
Breathability of the fabric
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 vapor generated by physical activity evaporates 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 ββof the Trek 700 overpants:
RET < 8 for the lightest fabric
RET < 12 for the most resistant fabric
How to restore water-repellent properties?
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:

A score for comparing the products’ environmental impact
The product’s environmental impact is calculated over its entire lifecycle 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, pants, backpacks, etc.) with each other. Decathlon is committed to displaying the environmental information of its products. For more information: http://sustainability.decathlon.com/
