How warm is this down jacket?
This down jacket, worn as a 3rd layer, has been validated for an active comfort temperature of -10°C, during a protocolized test in a thermal chamber. The mannequin wears a long-sleeved synthetic t-shirt and a light fleece. He walked in a simulated 5 km/h wind. We also tested the model statically. Its comfort temperature is 0°C.
The advantages of duck down and feather filling
Down's capacity to expand gives it 3 qualities for mountain sports:
- Thermal insulation thanks to the air trapped in the down and feathers.
- Ultra-lightness: with equal warmth, feather is lighter than synthetic wadding. This saves even more weight in the backpack.
- Ultra compressibility.
How do you measure the loft of down and feather fillings?
Loft represents the thermal insulation capacity of down by "trapping" a certain volume of air. It is expressed in cuin. So, the more lofty the down (the higher the cuin number), the more space it occupies, the more air it traps, and therefore the more insulating it is. For this down jacket, filled with 90% down and 10% feathers, the loft is guaranteed to be greater than or equal to 660 cuin (international standard).
Component water repellency (not to be confused with waterproofing)
A fabric's water repellency is its ability to let water slide off its surface without absorbing it. This means the fabric doesn't become waterlogged, and remains light and warm. The fabric of this down jacket is water-repellent, but we advise you to wear a waterproof jacket over it for prolonged exposure to the rain. Water repellency is achieved by a treatment applied to the outer face of the fabric, but it can be altered with use. We advise you to reactivate it each time you wash.
How do I care for a down comforter?
Down jackets are worn all winter long and will certainly need to be washed. But the less you wash it, the more it retains its thermal insulation and water repellency.
Our advice:
1/ Machine wash with a detergent for down or technical sportswear, at 30°, with 2 or 3 tennis balls. Spin gently.
2/ Tumble dry on cotton setting, with 2 or 3 tennis balls, repeat 2 or 3 times until completely dry.
Got a snag? Here's how to repair your down jacket
On a trek, a tear in your down jacket can happen! The good news is that it can be repaired with a patch to prevent the tear from getting bigger or feathers from escaping. Don't feel comfortable doing the repair yourself? Don't panic! Some Decathlon workshops offer an in-store repair service to mend your down jacket using an iron-on patch.
How to reactivate water repellency?
After cleaning your down jacket, we recommend using a water-repellency reactivator liquid to maintain the hydrophobic properties of the outer fabric. It regenerates the fabric's water repellency and optimizes the performance of your garment throughout its lifetime.
