Men's Mountain Trekking Down Jacket - Comfort -18°C - TREK 900 - Black

This down jacket, worn as a 3rd layer, has been certified for an active comfort 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. We have also tested this model in "static" mode, the comfort temperature is -5°C in this case.

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 only using down from ducks reared for their meat and plucked after slaughtering. We have been awarded RDS certification (Responsible Down Standard) by a third-party organisation. http://developpement-durable.decathlon.com/documents-et-rapports/documents/

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).

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 material of the quilted jacket is water repellent. It makes drops of water run off the surface, which delays the time it takes for water to get inside the padded jacket. What's more, the shoulders and hood of the padded jacket, which are more exposed to the rain, are waterproof. We use a thicker fabric (69 g/sqm, 20 Denier) laminated with a polyurethane membrane. We nevertheless recommend wearing a waterproof jacket over the quilted jacket in the event of prolonged exposure to the rain.

A fabric is water repellent when it allows water slide over its surface without seeping in. This prevents the fabric from swelling, and keeps it lightweight 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
