Waterproof Ultra Compact 20 litres Extra Backpack - Blue

We conduct laboratory tests to approve the components: fabrics, buckles, straps, foams, zips, etc. Example, for a fabric: resistance to wear, tearing, colour-fastness in UV rays, washing, waterproofing, etc. A final test on the finished product simulates the kind of treatment to which it will be subjected over several years, to assess the strength of the assembly.The backpack is filled with weights and placed on a dummy that reproduces the movement of fast walking through thousands of cycles.

The volume of each backpack is measured using a standardised method: we fill the main compartment as well as each pocket with little balls. We then empty the balls into a graduated container which provides the equivalent volume in litres.

The product's environmental impact is calculated over its entire life cycle using different indicators. An overall score from A to E is given to help you easily identify the most environmentally-friendly products by comparing products of the same type (T-shirts, trousers, backpacks, etc). Decathlon is committed to displaying the environmental data of its products. For more information: http://sustainability.decathlon.com/
