Men's Mountain Trekking Down Jacket - TREK 500 -10C Black

This padded jacket, worn as a 3rd layer, has been certified for an active comfort temperature of -10°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 0°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 low weight: 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).
So, 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 660 CUIN or more (European standard).

RDS or “Responsible Down Standard” is a worldwide certification issued by an independent organisation to volunteer brands.
This standard enables us to guarantee the origin of the feathers in accordance with our commitment to use responsible materials. Our suppliers commit to using only goose and duck feathers bread for their meat and slaughtered before down and feather collection.

A tear on a padded jacket can happen when trekking! The good news is that it can be repaired and you can avoid the tear getting bigger or feathers coming out.

Don't you feel at ease carrying out this repair yourself? Don't worry! Our in-store Decathlon workshops offer a repair service to mend your padded jacket using a heat-bonded patch.

The water repellent property of a fabric is its ability to make water run off its surface without absorbing it.
This prevents the fabric from swelling, & keeps it lightweight & warm.
The material of the quilted jacket is water repellent; we therefore recommend wearing a waterproof jacket on top in case of prolonged exposure to rain.

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.

Once you have cleaned your padded jacket, we recommend you use a water-repellent reactivator spray to preserve the hydrophobic properties of the outer fabric
