Use of a robust fabric (5.2 oz/sqm; 70 denier) on the areas to be protected
—specs—
Hybrid construction
Combination of a durable and protective fabric (5.2 oz/m2; 70 Denier) on areas to be protected from friction (knees, lower leg, buttocks) and a light and breathable fabric (3.8 oz/sqm; 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.
Hook at bottom of pant leg 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 450 liters of water/sqm/hour for 4 hours. This test reproduces the conditions of a thunderstorm in the mountains.
Sizing
Slightly fitted cut to limit having too much material and weight.
Choose your usual size or a size above if you are wearing them over very thick pants.
Inside leg length: 86.6″ in size 36 (M)
Width of pant hem: 20.1″ in size 36 (M)
Breathability of the fabric
To find out if a fabric is breathable, we test its evaporative resistance RET (ISO 11092 standard). The lower the fabric’s resistance, the more the water vapor evaporates, and the higher the fabric’s breathability.
We consider that:
RET < 9 = very breathable fabric
* 9 < RET < 12 = breathable fabric.
Here are the breathability values for the Trek 500 overpants:
>Most durable fabric: RET < 12 (or 8 lbs/sqm/24 h, standard JIS1099A)
>Lightest fabric:RET < 8 (or 2972 g/sqm/24 h, standard JIS1099A)
How to restore the water-repellent properties?
The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it.
As a result, your overpants do not soak up water and stay light 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 different indicators. An overall ABCDE rating is given to help you easily identify products with the best environmental performance by comparing and contrasting products of the same type (T-shirts, pants, backpacks, etc.).
Decathlon actively promotes this environmental rating initiative.
