Our team of mountain trekking enthusiasts designed this jacket for walking in cold or windy weather while remaining completely protected Waterproof jacket using the combination of a lightweight, breathable fabric and a sturdy fabric to help protect you from the elements.
Use of a robust fabric (147 g/sqm, 70 Denier) on the areas to be protected.
Combination of 2 fabrics resistant to 20,000 mm water pressure after 5 washes.
Double slider, water-repellent ventilation zip under the arms.
RET < 8 for the lightest fabric, RET < 12 for the most resistant fabric
Folds into its hood and stays compressed with a hook.
The hybrid construction reduces the weight to 470 g in size M.
Freedom of movement
Preformed elbows, adjustable hood, accessible pockets when wearing a backpack.

LEVEL OF PRACTICE
Combination of a strong and protective fabric (147 g/m2; 70 Denier) on areas to be protected from friction (shoulders, outer arms, front and back hem) and a light and breathable fabric (109 g/m2; 20 Denier) elsewhere. Back 2 cm longer than the front to ensure maximum protection and to cover the thermal layer 2 underneath if necessary.
Completely adjustable hood height and depth. Semi-rigid visor with integrated mesh headband to provide a high level of protection and support. The high stand-up collar effectively protects the lower face.
2 hand pockets that remain accessible even when carrying a backpack and a YKK AquaGuard waterproof zip. There is a mesh pocket for a mobile phone inside the right pocket to keep it safe and prevent it from falling out when you open your pocket.
Features a waterproof YKK AquaGuard zip along the entire length with an inside flap providing protection from the wind. Folded underflap on the hem to facilitate fastening of the zip. Double slider allowing opening from the bottom of the jacket. Soft fabric flap at the top of the collar to protect the chin.
Double tightening with an elastic cord and toggle at the hem. Velcro-adjustable sleeves covering the wrist. The gusset on the wrist makes it easy to wear gloves with the jacket.
Water resistance of the fabric
A fabric's resistance to water pressure is measured by the height of a column of water that can be supported by the fabric in mm (test based on the ISO 811 standard). The higher the water pressure, the more waterproof the fabric. Here are the waterproofing values of the Trek 500 jacket: 25,000 mm before washing for the lightest fabric (11,000 mm after 5 washes) 20,000 mm before washing for the most durable fabric (17,000 mm after 5 washes)
Water resistance of the jacket
The water resistance of the jacket was tested under rainfall of 450 litres of water/sqm/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 ISO 11092 standard). The lower the fabric's resistance, the more the water vapour 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 of the Trek 700 jacket: RET < 8 for the lightest fabric RET < 12 for the most resistant fabric
How to reactivate the water repellent property?
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.fr/conseils/comment-reactiver-la-deperlance-de-sa-veste-a_86425
A score for comparing products' environmental impact
The product's environmental impact is calculated over its entire life cycle using different indicators. An overall score from A to E is given to help you easily identify the most eco-friendly products by comparing them with products of the same type (T-shirts, trousers, backpacks, etc.) Decathlon is committed to visually displaying environmental information.

This jacket has been tested and validated in the field in genuine conditions. It was worn for 5 weeks by several people who undertook the Grande Traversée des Alpes (GTA) in late spring 2017.
