HOW TO POSITION MY YOKE-STYLE HARNESS

HOW TO POSITION MY YOKE-STYLE HARNESS

Contrary to popular belief, determining the right backpack size has no relation to height, but rather the length of the torso.  Torso length is measured from the top of your hip bones to your shoulders, and typically denotes the location of traditional shoulder straps.  Some pack systems have adjustable attachment points for shoulder straps to accommodate a range of torso lengths.  The Pack Mule and Pack Rabbit frame are such systems.  However, unlike traditional shoulder straps "yoke-style" harness systems require slightly different placement.  Yoke-style harnesses are intended to drape over the shoulders and not hang from the back of the neck**.

Follow the Steps outlined below to determine a base-line for positioning your yoke-style harness on the Pack Rabbit and Pack Mule frame systems. Fine-tune adjustments may be required, based on individual preferences and comfort.

  1. Locate your C7, or 7th cervical vertebra.  Tilt your head forward. Feel along the base of your neck for a bony bump, the one that protrudes farthest from your spine (located where the slope of your shoulder meets your neck).
  2. Locate your iliac crest, or hip shelf. Run your fingers down the sides of your rib cage until you reach the first hard spot, this is your hip bone. Place your hands on top with thumbs pointing behind you. This iliac crest serves as the “shelf” of your pelvic girdle.  Draw an imaginary line between your thumbs to the point where it intersects with your spine.
  3. Using a flexible measuring tape, measure the distace along the spine between the C7 vertrbra and the hip shelf. This measurement is your torso length.  (See diagram 1 below)
  4. Using the flexible measureing tape, measure that same distance along the vertical center of the Pack Rabbit or Pack Mule frame and mark that point. (See diagram 2 below)
  5. From the marked point, drop down 3 inches to locate the appropriate position to attach your yoke-style harness.

**If rubbing occurs along the back of the neck, the harness is attached too high on the frame.  Relocate the harness set to a lower position.
