Technical Information

Backpack technical tests.
We conduct lab tests to validate the following: fabric, buckles, straps, foam and zips. For example, for a fabric: resistance to abrasion and tearing, colour fastness in UV light and after washing, waterproofing, etc. Then the finished product undergoes an accelerated test replicating the stresses on the bag over several years to test the strength of the assemblies: We fill it with weights and place it on a dummy that reproduces thousands of fast walking movements.
10-year technical partnership warranty
The Strenfit component brand, Forclaz's partner for researching and testing its components and assemblies, conducted tests simulating backpack ageing. These tests were conducted on the components, the seams and the finished product. The results of the tests are used by Quechua and Strenfit to guarantee the tested bags for 10 years from the purchase date on the till receipt.
How to pack a backpack?
Put your bedding at the bottom. Carry heavy gear (tent, stove, food) closest to your back. Pack your clothes around these items. The groundsheet should be placed under the flap and the tent beneath the pack if there is no space inside. Keep a rainproof jacket and fleece close at hand. Place small items that are needed during the day (sun cream, map, glasses etc.) in the pockets. The water bladder should be positioned in the compartment that is generally alongside the back.
How is backpack volume measured?
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 to measure the equivalent volume in litres within a few percentage points. The unloaded weight provided is that of our reference sample. There may be slight variations.
A rating to compare the environmental impact of the products
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 eco-friendly products by comparing them with products of the same type (T-shirts, trousers, backpacks, etc.) Decathlon is committed to visually displaying environmental information.

Why are our rain covers coloured grey?
The great colour is neutral and therefore consumes less dye. The component is made of BITON: as a result, the environmental impact of the MT900 70L is 7.3% less than the former model: symbium access. By using dope-dye for the lining materials, much less water is consumed than a more brightly coloured fabric. It is by taking small measures of this kind that Forclaz is demonstrating its commitment to improve the environmental impact of its products.

Product test
All our backpacks are tested in the field by users who represent the target market under the same conditions as you would encounter in use. In particular, our "Mission Tests" bring together the product manager with people who are not affiliated with QUECHUA to test, improve and validate our products. This specific model was approved by hikers touring Mont Blanc in June 2017.
