Technical Informations

Laboratory Testing
We carry out laboratory tests to validate all component parts: fabric, buckles, straps, foam and zips. For example, for fabric: resistance to wear, tearing, colour-fastness under UV rays, washing, waterproofing. 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 weighted then placed on a dummy which then reproduces the movement of fast walking over thousands of cycles
10-year warranty, technical partnership
The heavy stitching research and development department, Quechua's partner for researching and testing its components and assemblies, conducted tests simulating backpack ageing. The tests focused on components, seams and the end product. As a result of these tests, Quechua can guarantee all bags tested for a duration of 10 years from the date of purchase indicated on the sales receipt.
10-year guarantee, conditions
The guarantee covers any backpack faults, except those caused by normal wear and tear and improper use. This special 10-year guarantee will only be granted upon presentation of the product and sales receipt. If the product is covered by the warranty, it will be repaired or exchanged for free. This commercial warranty does not exclude applicable legal warranties depending on the country and/or State.
How is 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. Then we empty these balls into a graduated container, which gives the equivalent volume in litres.
How do I adjust my backpack?
1 - Loosen all the straps (straps, hip belt, load adjuster straps). 2 - Put the backpack on. 3 - For backpacks with a capacity of 50 L or more, place the hip belt correctly (it should sit over the pelvis) and tighten it. For smaller backpacks, the belt should be placed around the waist. 4 -Tighten the shoulder straps. 5 - Adjust the load adjuster straps as needed.
How to pack a backpack?
Put your bedding at the bottom. Put heavy gear near to the back. Pack your clothes around these items. Keep a rainproof jacket and fleece close at hand. Place small items for daily use (sun cream, map, glasses etc.) in the pockets. If carrying a hydration pack (water bladder), this should be placed in its special pocket along the back.
Environmental measures
The environmental impact of the product is calculated over the entire lifecycle of the product using different indicators. A global ABCDE rating 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, backpacks, etc.). Decathlon is a voluntary participant in this environmental labelling initiative. For further information:

Used for 1 week or less
Too early for me to comment objectively, however I'm pleased with my purchase as I think it offers a lot of features for the price. I will update once I have used the sack.
Used for 3 to 6 months
firm favorite, first piece of kit I look for
Great pack
Used for 2 to 8 weeks
Bought this item for replacing my old Decathlon pack after years of toll. With a modern design that includes hip pocket for today's essential phone! Not sure the base zip is necessary given this is a small/daysack.
