Backpack Sizing Chart

Pack size is based on two measurements: torso length and waist (hip belt) circumference.

How to Measure

Waist: Measure around your waist just above the top of the hip bones, roughly two fingers below the belly button.

Torso: Measure from the bony bump at the base of the neck (C7 vertebra) down the spine to the point behind your belly button.

Notes: Pack capacity does not change between sizes — only the yoke and waist belt differ. If you fall between waist belt sizes, we recommend sizing down so the belt can snugly secure around your hips. The listed ranges leave a little extra adjustment room for extra clothing layers.
