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 necessary. After a few years, you can refresh the water repellent properties of the fabric using a waterproofing spray.
Storage Tips
Store your bag in a dry place.
Restricted use
Check carry system if you are over 1.80 m (5'11'') tall.

Backpack technical tests.
Backpack components are approved in laboratory tests, including fabric, buckles, straps, foam, zips, etc. Fabrics are tested for resistance to wear, tearing, colour-fastness in UV rays, washing, waterproofing and more. 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 reproduces fast walking over thousands of cycles.
10-year guarantee, technical partnership
The Strenfit component brand, Quechua's partner for researching and testing its components and assemblies, conducted tests simulating backpack ageing. These tests were carried out on the components, seams, and finished product. As a result of these tests, Quechua and Strenfit can guarantee all bags tested for a duration of 10 years from the date of purchase indicated on the sales receipt.
Conditions of the 10-year guarantee
This guarantee covers backpack defects, excluding those resulting from normal wear and abnormal use. This special 10-year guarantee will only be honoured upon presentation of the product and receipt. If the product is under guarantee, it will be repaired or exchanged free of charge. This commercial guarantee does not affect any statutory guarantees that are applicable in the country of purchase.
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. Then we empty these balls into a graduated container, which gives the equivalent volume in litres.
Environmental measurements
In collaboration with Quechua, Oxylane is proud to present information on the environmental impact of hiking backpacks and their life cycle. This is the result of experiments done starting in July 2011 in cooperation with the French Ministry of the Environment. 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 http://www.oxylane.com/20/demarche-environnementale
How to adjust your backpack
FIRST, LOOSEN all straps (shoulder straps, belt, load adjuster straps). PUT THE BACKPACK ON. For backpacks with a capacity of 50 L or more, PLACE THE HIP BELT CORRECTLY (over 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 to suit you.
How to adjust bag height
" First set to the estimated height and then adjust the bag as needed (see "How to adjust 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 pack a backpack
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 frequently-used items (sunscreen, map, glasses, etc.) in the pockets. If carrying a hydration pack (water bladder), this should be placed in its special pocket along the back.
The Symbium EasyFit system
The freedom of movement provided by Symbium and the EasyFit concept allow you to simply and intuitively adjust your backpack to suit your body type while it is on your back in order to ensure maximum comfort.
EasyFit effectiveness tests are carried out by our Research and Development teams.
User-friendly design: adjustment time is 2.3 times shorter with EasyFit backpacks; with the EasyFit system, you'll never have to backtrack. Furthermore, the EasyFit system does not affect the quality of the adjustments when compared with a standard adjustment system. EasyFit was rated significantly more comfortable on a 4% Friedman statistical test; 6 times more good adjustments were observed.
"Air Cooling" certified packs are subjected to a laboratory test that measures the effectiveness of the ventilation of the carrying system: a heated and perspiring mannequin is used to scientifically and objectively measure the pack's capacity to reduce perspiration. This label is only given to packs that perform significantly better than a "basic" model in the range (without any particular cooling system). We also compare them to other products on the market
