Please note:

The height range given for each Longueur de dos is only a guideline and may not be right for your particular proportions. We always recommend trying on our rucksacks before you make your final choice.
Typically, the hip-belt should wrap around the top of the pelvis, so that the hips are able to share the overall load (see diagram). But you may wear your rucksack differently, and this will also affect your choice of size. For example, some climbers carry their rucksack “high” – in other words, around their waist and thus above the pelvis – and may prefer a rucksack with a shorter Longueur de dos.
