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.
Store your bag in a dry place.

The Symbium Access system
The Symbium Access combines the advantages of the Symbium system that enables freedom of movement thanks to the waist adjustment around the lumbar region. it is also equipped with the Access System: 1 pocket that can be easily moved to the front of the upper body: providing easy access to many items while walking, possibility of reading a map easily. This also allows you to shift some of the weight to the front, helps the hiker to have a straighter back and a more normal stance.
Backpack technical tests.
Backpack components are approved in laboratory tests, including:fabric, buckles, webbing, foam, zips,etc. Fabrics are tested for: resistance to wear, tearing, colour-fastness under 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 weighted, then placed on a dummy which reproduces the movement of fast walking through thousands of cycles.

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, with a margin of a few %. The weight indicated is that of our benchmark sample. There may be slight variations.
Symbium Access backpack ventilation
"Air Cooling" certified backpacks are subjected to a laboratory test that measures the carrying system's ventilation effectiveness A heated and perspiring mannequin is used to scientifically and objectively measure how well the pack limits 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 with other products on the market.
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 (it should sit 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 as needed.
Adjusting your backpack height?
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 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 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.
