Product Reviews

This jacket is warm and beautiful.
Tried this jacket in snowfall and icy area, kept me alive.
Nice inexpensive hiking camp jacket. I would order it again.
Product also good and good service, but billing processing is poor so please increase your billing counters.
Very warm and very comfortable wearing. The fabric is soft and the grey color variant looks amazing in daylight.
It is a warm jacket but packing is coming out.Either product is defective or stitching threads are weak.

Its not warm enough in 1°
Hello Arindam
Thank you for your valuable review. We are sorry for the issue you faced. Our Trek 100 jackets are tested on the ground with a group of external trekkers with proper layering and are rated for -5 degrees while trekking, However, the static temperature protection wouldn't be -5 and we also believe that temperature is subjective and depends on many factors for person to person and that is why the rating is given to guide our users on the basis of the actual test.

How warm is this padded jacket?
This padded jacket, worn as a 3rd layer, has been certified for an active comfort temperature of -5°C during a standardised test in a thermal chamber.The model is wearing a synthetic long-sleeved t-shirt and a light fleece underneath. It works with a simulated 5 km/h wind.We have also tested this model in "static" mode; the comfort temperature is +5°C in this case.
The advantages of a duck down and feather filling
The filling power of down has 3 advantages for mountain sports:- Thermal insulation thanks to the air trapped in the down and feathers- Ultra lightweight: down is lighter than synthetic wadding while offering the same degree of warmth. This saves even more weight in your backpack- Ultra-compressible
How to measure the fill power of a down and feather wadding?
The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" air. It is expressed in CUIN (cubic inches).Down with a higher fill power (higher CUIN number) will occupy more space, trap more air and provide greater thermal insulation.For this down jacket with its 85% down/15% feathers filling, the fill power is guaranteed to be 800 CUIN or more (European standard).
* what is rds certification?
Thanks to our traceability system, we can guarantee the origin of the feathers in accordance with our commitment to use responsible materials. Our suppliers commit to using only feathers from ducks raised for their meat and plucked after slaughter.We have been awarded RDS certification (Responsible Down Standard) by a third-party organisation.http://developpement-durable.decathlon.com/documents-et-rapports/documents/

How to care for a down and feather jacket?
The down jacket can be worn throughout the winter and will certainly need to be washed. Follow our guidance by clicking on the link below:https://www.forclaz.co.uk/advice-alias/how-should-i-look-after-my-down-jacket-tp_2579In brief:1/ machine wash, 30°, with 2 or 3 tennis balls. Gentle spin cycle.2/ tumble dry with 2 or 3 tennis balls, repeat 2 or 3 times until it is completely dry
In case of rain
The material of the down jacket is water-repellent. It lets drops of water roll off the fabric, delaying water getting in the jacket and giving you time to find shelter. We nevertheless recommend wearing a waterproof jacket over the down jacket in the event of prolonged exposure to the rain.
Water-repellent property of component (not to be confused with waterproofing)
The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it.As a result, the fabric does not soak up water and stays light and warm.The fabric is made water-repellent by treating its outer surface, however this property may deteriorate with use.We recommend that you restore it after each wash.
How to restore water-repellent properties?
The water-repellent treatment becomes less effective with time, washing and use.Here is how to restore the water-repellent properties of your padded jacket!https://www.quechua.co.uk/advice/how-do-you-restore-water-repellent-properties-your-jacket-a_86426You can also use the care product: Treatment restoring water-repellent propertieshttps://www.decathlon.co.uk/txdirect-wash-in-300ml-id_8401685.html
