The fleece component keeps the air inside thanks to the volume created by its texture; this air keeps the body warm with its natural insulating properties. It is the abrasive nature of the knit that helps keep the air in.
Durability of the components
Abrasion and friction resistance test: for example, we check that fleeces do not pill using tests conducted in the laboratory. Colour retention test: the colour fastness is verified to make sure that the colours do not bleed when coming into contact with saliva. Ageing test: repeated washing must not affect the properties of the fabric, its behaviour, thickness or appearance.
A score to compare the products' environmental impact
The product's environmental impacts are calculated over its whole lifecycle and with different indicators. An overall rating of ABCDE is provided to help you easily identify products with the best environmental performance by comparing products of the same type with each other (t-shirts, trousers and backpacks). Decathlon is a voluntary actor in this environmental labelling process. For further information: http://sustainability.decathlon.com/

Store on a hanger or folded in a clean, dry place.
We carry out 2 types of thermal testing: - either a test of the material of our fleeces. - or testing on a thermal manikin in a thermal chamber. We reproduce the conditions of temperature, wind (5 km/h) and humidity that you would encounter in the mountains walking at 5 km/h in our testing chambers. These tests allow us to validate our design choices. So we can adapt our thermal insulation where you most need it.
