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 of this lining 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 model, 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 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.To reactivate it, follow the guide:
