Men's Mountain Trekking Down Jacket - Comfort -5°C - TREK 100 - Navy

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 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

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).

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/

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.

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.

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
