Technical Informations

Durability of the components
Resistance to wear test: the fabric, for example, is laboratory tested to check that the fleece doesn’t pill. 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.
Can be worn as shorts
The trousers can be converted into shorts using the zips on the legs, for wearing in any weather and on all types of hike. Fastening tab on the lower legs.
Technical details
An adjustable elasticated waistband with buttons allows trousers to be adjusted to fit children of the same size with different body shapes. 2 hand pockets and 2 side thigh pockets including 1 zipped.
Sun protection
The fabric offers the best protection from the sun: go for long sleeves, trousers and hats with wide brims. Be aware, simply wearing a T-shirt is not adequate protection: the thickness of the fabric, the density of the weave and even the colour can impact the rate of UV filtered. the label UPF 40+/ 50+ guarantees compliance with European standards. A UPF 40+ rating means that 97.5% of rays are blocked out, 50+ that more than 98% of rays are blocked out.
A score for comparing products' environmental impact
The product's environmental impact is calculated over its entire life cycle using various indicators. An overall rating from A to E is given to help you easily identify products with the best environmental performance by comparing and contrasting products of the same type (T-shirts, trousers, backpacks, etc.). Decathlon actively promotes this environmental rating initiative. For more information:
