How can I pack my bag for maximum comfort?

Put your bedding at the bottom. Put heavy gear (tent, camp stove, food) near the back. Pack your clothes around these items. The ground sheet can 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 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.

How do I adjust the height of my bag?

Set the bag for the height you think will be correct and then adjust it (see. "Adjusting your backpack").
With the belt on your pelvis, put the straps around the front part of your shoulders and the load adjuster straps (which are sometimes also height-adjustable) at an angle of around 45° (they should never be horizontal or vertical).
When trying it on, if the back seems too short or too long, readjust and try again until you are satisfied.

How to adjust your backpack?

First, loosen all the straps (shoulder straps, belt straps, load adjuster straps).
Put the backpack on. For bags with a capacity of over 50L, place the belt on the hips (the belt must wrap around the iliac bones of the pelvis) and tighten it.
For smaller backpacks, the hip belt should be placed around the waist.
Tighten the shoulder straps.
Finally, adjust the load adjuster straps as needed.

Environmental measurements

Decathlon has chosen to inform you about the environmental impact of trekking backpack products for the duration of their life cycle. This work follows an experiment that began in July 2011 with the French Ministry of Ecology. Scores ranging from A to E were awarded based on comparisons between Quechua's backpacks only. Details on this project and the calculation methods used are available at

How is backpack volume measured?

The volume of each backpack is measured using a standardized 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 gallons, with a margin of a few %.
The weight indicated is that of our benchmark sample. There may be slight variations.

10-year guarantee

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 under guarantee, it will be repaired or exchanged for free. This commercial guarantee does not affect any statutory guarantees that are applicable in the country of purchase.

Product Testing

We test the resistance of the bag to abrasion, tearing, the resistance of colors to UV rays and washing and waterproofing. Tests are conducted in the field and laboratory.\nThen a mannequin reproduces wear on the weighted sac via fast walking movements for thousands of cycles to test the resistance of assemblages.\nThe components (fabric, buckles, straps, foam, zippers, etc.) are also tested separately. As a result we can guarantee these bags for 10 years.

Care Instructions

To ensure materials retain their properties (especially waterproofing), we recommend you do not machine wash, tumble dry, dry-clean, or bleach your backpack. Do not iron. To clean your backpack by hand, use warm soapy water and a brush if needed. After a few years of use, you should renew the water repellent properties of the fabric using a waterproofing spray.
