What size is right for you?

When it comes to backpacks, it’s not your height that matters, but your back length. Two people who are both 1.80 m tall can have completely different back lengths, and it’s precisely this that determines whether the hip belt sits on the iliac crest and the weight actually lands on your hips instead of your shoulders.

Here’s how to measure: Tilt your head forward; you’ll feel a distinctly protruding vertebra at the base of your neck. From there, have a second person measure along the spine up to the level of the upper iliac crest—that is, where you place your hands on your hips. This measurement is your back length. For the hip belt, measure the circumference at the level of the iliac crest, not at the waist.

• √ S/M: Back length 44 to 52 cm, hip circumference 71 to 127 cm
• √ L/XL: Back length 50 to 58 cm, hip circumference 76 to 127 cm
• √ The hip belt and shoulder straps are also individually adjustable

If you fall within the overlap range, choose the smaller size. The back length can be adjusted on the backpack, and a more compact fit ensures a more stable feel. If you’re unsure, give us a call or stop by—we’ll help you adjust it.
