Technical Information

Hybrid construction
Combination of a strong and protective fabric (147 gr/m2, 70 Denier) on areas to be protected from friction (shoulders, outer arms, front and back hem) and a light and breathable fabric (109 gr/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 with waterproof YKK AquaGuard zip fastening.There is a mesh mobile phone pocket inside the right pocket.
Front zip
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 the 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
We test a fabric's resistance to water pressure by measuring the height of a column of water supported by the fabric in mm (test based on the ISO 811 standard). The better the fabric resists pressure, the more waterproof it is. Components with a 2000 mm rating can withstand the pressure of a 2000 mm column of water (which is equivalent to a rain shower lasting two hour). With a water resistance greater than 10,000 mm, the TREK 700 jacket provides an extremely high degree of water resistance.
Water resistance of the jacket
The water resistance of the jacket 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.
Breathability of the fabric
To find out whether a fabric is breathable, we measure its evaporative resistance or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more 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

Product test
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.
