To accurately measure your torso length for a correct pack fit, grab a buddy and follow the steps:

  • Standing upright, tilt your chin to your chest.
  • Locate the largest lump on the back of your neck. It should be located close to the base of your neck.
  • From this large bone, measure (with the flexible tape) down the length and natural curvature of your spine to the top of your waist band, the top of which is resting on the top your hipbone. This measurement in inches is your torso length.
