Measuring Your Torso Length


Torso measurement is the best guide we have for proper pack fit, but it isn’t foolproof, there are many other factors which will determine a proper fit. If your torso measurement is between 2 sizes or doesn’t make sense for your height, email and he can guide you along. If you are between sizes on the hipbelt it’s best to go with the larger size, it gives you more padding and puts the pockets in a better position.


  • 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.
