Size Guide

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.
