This down jacket, worn as a 3rd layer, has been certified for a comfort activity temperature of -18°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. In our heat comparison tool, it represents 4 stars. We have also tested this model in "static" mode; the comfort temperature is -5°C in this case. Heat-sealed compartments.

Ethical down certified by RDS (Responsible Down 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 are committed to using only feathers that come from ducks that are bred for their meat and which are plucked after slaughtering. http://sustainability.decathlon.com/media-reports/documents/

For this down jacket with its 85% down/15% feathers filling, the fill power is guaranteed to be 660 CUIN or more (European standard). The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" air. So, down with a higher fill power (higher CUIN number) will occupy more space, trap more air and provide greater thermal insulation.

The durability and fill power properties of down give this jacket 3 qualities for hiking: - 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 main stitching of the compartments containing the down and feather are heat-sealed to prevent the loss of feathers.

The material of the quilted jacket is water repellent. It allows drops of water to slide off the fabric which delays the penetration of water into the quilted jacket while you get out of the rain. The shoulders and hood of the jacket, which are more exposed to the rain, are waterproof. We nevertheless recommend wearing a waterproof jacket over the quilted jacket in the event of prolonged exposure to the rain.

Here are a few tips: close all the zips on your down jacket and put it in the washing machine (synthetic cycle at 30°C). To maintain the filling and warmth, it's even better to add 2 tennis balls in the machine. Be sure to select a gentle spin cycle: a fast spin cycle may create balls of feathers that are difficult to break up.

When you take your down jacket out of the washing machine it will seem as if the down has gone THE TUMBLE DRYER is the best way to restore the fill power of the feathers Put your down jacket in the tumble dryer with 2 tennis balls Run 2-3 drying cycles. If you do not have a tumble dryer you can completely dry your down jacket on a drying rack by turning it over and tapping regularly. https://www.forclaz.fr/conseils/comment-entretenir-sa-doudoune-en-plumes-tp_101
