Technical Information

Durable materials
This polyamide fabric that uses 20 denier thread can withstand 20,000 abrasion cycles. Martindale test, 12947-2 standard Outer: 100% polyamide fabric 39g/sqm, 20 denier Lining: 100% polyester fabric 35g/sqm, mix of 15 to 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 (25% recycled). The wadding is made from silicone-coated spiral fibres that make it highly compressible and highly durable. Despite its low thickness, it has high insulation properties thanks to the air trapped inside, and remains lightweight. It retains its warmth even when wet.
Do you know why the inner lining of your padded jacket is grey?
Because the fabric we use reduces CO2 emissions by 40%. The fabric used is innovative because it mixes a dope-dyed black yarn and an undyed yarn. Compared to a classic dyeing process, this process reduces by: - 66% fine particle emissions (PM2.5) - 74% eutrophication of fresh water - 68% eutrophication of sea water
Additional sustainable development information
On the black Trek 100 and blue Trek 100 models, the outer fabric uses a clean dyeing process known as dope dyeing (the thread is dyed before the yarn is woven) reducing CO2 emissions by 36%. More information:
Water repellent property of component (not to be confused with waterproofing)
The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing itThis prevents the fabric from soaking up water & keeps it lightweight & breathableThe fabric is made water-repellent by treating its outer surface, however this property may deteriorate with useTo reactivate it, follow the guide:
Inside flap under the zip that protects 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 elasticated bias binding

Product test
In November 2017, 6 trekkers (4 men and 2 women) with part of the Forclaz design team tested this padded jacket for four days in the Southern French Alps. We were then able to make the final modifications and validate it for mountain trekking use.
