Nouzové zeteplení

Díky sbalitelnosti do malého balíčku dobrá nouzovka při ochlazení. Celkově velmi úzká - jen pro hubené postavy.

Additional Product informations


Main fabric

  • 100% Polyamide

Main lining

  • 100% Polyamide


  • 100% Polyester

Check out the eco-design of this padded jacket!

The filling of this padded jacket is made from 70% recycled polyester fibres.For the lining, we use a “bi-ton” dyeing process where only one thread in every two is dyed. This dyed thread is also the result of dope dyeing which incorporates the colour pigments from the initial thread manufacture to avoid the use of dyeing baths and reduce our water consumption.This process can reduce CO2 emissions by 40% compared to traditional dyeing methods.

Want to know more about the wadding?

We use 100% polyester wadding (70% recycled) at 125 g/m².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.

Additional sustainable development information

On the black Trek 100 sleeveless jacket 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:

Durable materials

This polyamide fabric that uses 20 denier thread can withstand 20,000 abrasion cycles.Martindale test, Standard 12947-2.Outer: 100% polyamide fabric 39g/sqm, 20 denierLining: 100% polyester fabric 35g/sqm, mix of 15 to 20 denier threads

Water-repellent property of component (not to be confused with waterproofing)

The water repellent property of a fabric is its ability to make water run off its surface without absorbing it.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.

Pfc-free water-repellent treatment

On the Trek 100 sleeveless jacket, the water repellent treatment doesn't contain PFCs (perfluorocarbons), i.e. it is PFC-Free.PFCs are used to make fabric water-repellent, however they are toxic to the environment and people. By substituting PFCs with other technologies giving the same level of performance, we are reducing the environmental impact.

How to restore water-repellent properties?

Once you have cleaned your padded jacket, we recommend you use a water-repellent reactivator spray to preserve the hydrophobic properties of the outer fabric

How to repair a gilet?

A tear on a padded gilet can happen when trekking! The good news is that it can be repaired so the tear doesn’t get any bigger or to stop the synthetic fibres from escaping.Don't you feel at ease carrying out this repair yourself? Don't worry! Our in-store Decathlon workshops offer a repair service to mend your padded gilet using a heat-bonded patch.
