LOAD YOUR TECHNICAL BACKPACK PRISM


4 ESSENTIAL POINTS TO GUIDE YOU!

Incorrect load distribution in your backpack can lead to additional strain and possible pain or even injury due to imbalance.
For a good use of your backpack and to fully appreciate its comfort, you can follow the following recommendations, knowing that the weight of your backpack should not exceed a quarter of your own weight

1) Place the heaviest loads at the bottom of the bag, as well as the objects you use the least (change of clothes, sleeping bag if you are going to camp, etc.)

2) The centre of gravity of your backpack should be as close as possible to your body, so place the heaviest loads against your back (ideally in the middle of your back) and centrally (spine) so that you are not thrown off balance during your activity. In case of a fall, your back protector will protect you!

3) Keep the things you use the most within reach, on the top of the bag or in the outside pockets, without overloading these areas.

4) Finally, so that nothing moves in your backpack, use the helmet carrier as a compression strap by tightening it as much as possible.

Now set correctly your PRISM backpack for maximum comfort and don't forget anything with our checklists!
