MSN + MTN Pack Sizing

S M L
Torso Length 18 19 1/2 21
Sizing refers to body measurement, not pack dimensions, and are in inches.

How to measure

Finding the right pack size is all about your torso length, not your height. To find your torso length have a friend measure your spine using the steps below:

  1. Find the most prominent vertebrae (C-7) at the back of your neck (tilting your head forward helps). It’s the large bump at about the same level as the top of your shoulders.
  2. Find the top of your hipbone (the iliac crest). Follow this point around in a straight line to your spine.
  3. Stand up straight and lay a flexible measuring tape directly against your spine. Measure the distance between points 1 & 2.
