Technical Information

Resistant materials
This polyamide canvas uses 20 deniers thread, resists 20,000 cycles of abrasion.Martindale test, Standard 12 947-2 Outer:100% polyamide 39 g/sqm, 20 denier fabric Lining: 100% polyamide fabric (35g/sqm), a mix of 15 and 20 denier threads
Thermal insulation
This down jacket has been certified for a comfort temperature of -6° during a standardised test in a thermal chamber. The mannequin wears 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 2 stars.
Technical information on the wadding
We use 100% polyester wadding (70% recycled) at 100g/sqm on the body and 80g/sqm on the sleeves and hood. The wadding is made from silicon-coated spiral fibres that make it highly compressible and highly durable. Despite its thin design, it is highly insulating thanks to the air trapped inside and it remains low weight. It remains warm even when wet.
Do you know why the inner lining of your down jacket is grey?
Because the fabric we use reduces CO2 emissions by 40%. The fabric used is innovative because it mixes a self-dyed black thread and an undyed thread. Compared to conventional dyeing, this process makes it possible to reduce: • fine particle emissions by 66% (PM2.5) • eutrophication of fresh water by 74% • eutrophication of marine water by 68%
Additional sustainable development information
On the Trek 100 black and blue models, the outer fabric uses a clean dying process known as dope dying (the thread is self-dyed), reducing CO2 emissions by 36%. More information:
Water repellent property of the component (not to be confused with the waterproofing)
The water repellent property of a fabric is its capacity to make water run off its surface without absorbing it. This prevents the fabric from soaking up water, and keeps it lightweight and breathable. The fabric is made water repellent by treating its outer surface, however this property may deteriorate with use. In order to reactivate it, follow the guide:
Inside flap under the zip that protects you from the wind. Elasticated cuffs, Flap at the top of the collar to protect the chin. Tightening with an elastic cord and toggle at the hem.Hood with elastic bias binding

Excellent Jacket with no weight. It really works in cold atmosphere even on bike riding. Just wear a body warmer below it and move out for a tour in cold places. Only problem with it is that there must be a pocket inside for valuable things.

Excellent for winter
Not a down jacket
Used for 1 week or less
Why call it a down jacket? It’s not down, it does state on the spec that it’s polyester but I searched for a down jacket and bought one.
It will keep me warm enough but why describe it as down?
