Step 6 - Positioning the Upper Load Stabiliser Straps

Description

Where are the Upper Load Stabiliser Straps located?

The Upper Load Stabiliser Straps are located at the top of the Internal Staves. These two Upper Load Stabiliser Straps pulled simultaneously draw the upper backpack closer to the back.

What are the Upper Load Stabiliser Straps?

On Internal Frame Backpacks, the Upper Load Stabiliser Straps are adjustable straps that run from the Shoulder Strap at the top of shoulder, to an attachment point on the backpack, at the top of the Internal Staves. These Upper Load Stabiliser Straps allow you to adjust the distance between your back and your backpack.

What is the purpose of correctly positioning the Upper Load Stabiliser Straps

It is critical that the exit point, or pull position of the Upper Load Stabiliser Straps from the Shoulder Straps to the top of the backpack is correctly positioned. The optimum exit position of the Upper Load Stabiliser Straps from the shoulder is below the clavicle, 25mm to 40mm lower than the top of the shoulder. This ensures the pressure or pull of the backpack is placed equally on the shoulders and the chest. White Mountain Backpacks™ provide a sliding buckle on the Upper Load Stabiliser Strap above the Shoulder Strap D-Ring for finite positioning, but in our opinion, it is better to use a backpack of the correct size and set the Torso Length accurately rather than using this adjustment. This sliding buckle can, however, be moved as much as 25mm to optimize the position of pull from the Shoulder Straps

After setting the Torso Length correctly and positioning the exit point of the Upper Load Stabiliser Straps, you should find the Hip Belt positioned correctly across, or just below the Iliac Crest or hipbone. If this is not the case, you will need to adjust the Ladder Harness, Sliding Yoke Harness or independent Sliding Harness to increase or decrease the Torso Length to achieve correct positioning.

How do you use the Upper Load Stabiliser Straps

Pulling the two Upper Load Stabiliser Straps simultaneously draws the backpack closer to the back with the Internal Staves and backpack sitting squarely on the shoulders. This will place an even pressure on the shoulders through the Shoulder Straps. The Sternum Strap also plays an important role in transferring weight to the chest, and assists in keeping the Shoulder Straps in position, but more on the Sternum Strap later. On uphill hauls were it’s advantageous to have the weight close to your back, tighten these straps to pull the top of the backpack close to your body. Conversely, loosen the Upper Load Stabiliser Straps on downhill treks to adjust the centre of gravity. In hotter weather, loosening these straps will provide ventilation between the back and the backpack.

NOTE: Do not over tension the Upper Load Stabiliser Straps. Over tensioning and having these straps incorrectly pull at more than 45º from the Shoulder Straps, to the anchor point on the backpack, lifts the Shoulder Straps, renders the Sternum Strap ineffective and places excessive unnecessary stress on the chest. For an oversized backpack and a smaller Torso Length, reduce the angle of pull by positioning the Upper Load Stabiliser Straps to pull from lower on the backpack. To aid repositioning of the Upper Load Stabiliser Straps, all White Mountain Backpacks™ provide alternative anchoring positions, in the form of Ladder Lock Buckles, or Webbing Loops on the backpack harness. These secondary ladder lock buckles or webbing loops are located above the Internal Stave, approximately 5 cm below the original anchor position, on top of the backpack.

Use the Upper Load Stabiliser Straps to bring the backpack close to the back, with the Internal Staves and backpack sitting squarely on the shoulders, placing an even pressure on the shoulders through the Shoulder Straps. The Sternum Strap also plays an important role in transferring weight to the chest, and assists in keeping the Shoulder Straps in position, but more on the Sternum Strap later.

Important

Do not over tension these Upper Stabiliser Straps. Over tensioning or having these straps incorrectly pull at more than 45º angle from the Shoulder Straps to the anchor point on the backpack, lifts the Shoulder Straps and places excessive, unnecessary stress on the chest. For an oversized backpack and a smaller Torso Length, position the Upper Stabiliser Straps to pull from lower on the backpack. To aid repositioning of the Upper Stabiliser Straps , each White Mountain Backpacks™ backpack provides alternative anchoring positions in the form of Ladder Lock Buckles, or Webbing Loops, on the backpack harness. These secondary ladder lock buckles, or webbing loops, are located approximately 5cm below the original position.
