How to choose the right torso and hip belt sizes for your pack

Choosing the right torso sizeTorso length measurement

To choose the right torso size for your pack, you must first measure your torso length.  This can be easily done with a flexible tape measure and the help of a friend.

  1. Bend your neck forward to touch your chin to your chest.  Locate the prominent vertebrae on the back of your neck.  This is the C7 vertebrae.
  2. Locate the large bony protrusions on the side of your body formed by the sides of your pelvis.  These are your Iliac crests.  Adjust the waist band of your pants so the top of the waist band is level with the tops of your Iliac crests.
  3. With your head in its natural upright position, measure from the top of your waist band to the C7 vertebrae.

This measurement is your torso length.  Simply compare this measurement with the sizing charts below to choose the correct frame size for your new pack.

* Note: We have found that, particularly with our framed packs, for individuals who are in between sizes it is best to choose the smaller frame size.  If you choose to go up to the larger size, most times the shoulder straps do not wrap over the top of the shoulder, which can upset the balance of the pack, and the stay is too tall and can interfere with your head's natural range of motion.  In our framed packs, there is a 3" difference in actual torso length from size to size.  The actual torso length on the Aquilo and Kalais packs is: Small - 15", Medium - 18", Large - 21", X-Large - 24".  The actual torso length on the Aduro SL is S/M - 17.5", M/L - 19.5".


Choosing the right hip belt sizeHip belt measurement

The easiest way to choose the right hip belt size is to compare the waist size of your favorite blue jeans to the waist size in the fit chart below.  For the ideal hip belt fit your waist size should be withn the range for the belt size you are choosing (ex: I have a 33" waist, so I wear the medium hip belt.) For those who have waist sizes that do not fall neatly within  the fit range of a particular size, you should have at least 2" of foam beyond the front edges of your pelvis.  To check if you have chosen the right size hip belt, measure from the front edge of your pelvis on one side of your body, around your back to the front edge of your pelvis on the other side of your body.  Add 4" to this measurement, then compare this measurement with the padding length in the charts below.  The padding length should be at least your total measurement.
