    My Daughter Loves these!
    Lightweight, easy to switch from trousers to short

    My daughter absolutely loves these trousers. She has always liked the zip off trousers, and had outgrown her last sets. She is really happy with these ones. They convert to shorts very easily. The colour stitch under the seam take away the guess game of which leg belongs on which zip.The lightweight nature also allow for quick drying in our recent wet "summer".

Care instructions
Machine wash on normal cycle, 40°C max. Do not exceed the maximum machine load, as this can damage fabrics and wear them out faster. Softener: no restrictions. Do not use bleach. Drying: air dry or tumble dry on moderate temperature. Do not iron. Do not dry clean.
Storage Tips
Store on hanger or folded in a clean and dry place.


Durability of the components
Resistance test to wear: for example, we check that the fleeces do not pill using tests conducted in laboratories. 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 alter the properties of the fabric, its shape, thickness or appearance.
Can be worn as shorts
Trousers can be converted into shorts, using the zips on the legs, for wearing in any weather and on all hikes. Fastening tab on the lower pant 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 lateral thigh pockets including 1 zipped.
Sun protection
Clothing remains the best form of sun protection: opt for long sleeves, trousers and wide-brimmed hat. Note, wearing a T-shirt is not adequate protection: the thickness of the fabric, the density of the knit and even the colour can affect the level of UV rays blocked. UPF 40+/ 50+ certification demonstrates compliance with European standards. A UPF of 40+ means that 97.5% of all rays are blocked, and 50+ means that 98% of rays are blocked.
Comparative note on the environmental impact of the products
The product's environmental impact is calculated across its entire life cycle using different indicators. An overall ABCDE score is provided to help you easily identify the most environmentally-friendly products when comparing products of the same type (T-shirts, trousers, backpacks, etc.). Decathlon is a voluntary supporter of this environmentally-friendly labelling approach. For more information, visit: http://sustainability.decathlon.com/
