The SA (size adjustable) back system allows on-the-back and on-the-move adjustments to reduce muscle fatigue.

Fitting Instructions 

1

 

 

(1) Loosen off all of the straps. This will allow for the maximum size to be attained as a starting point.

(2) Put the rucksack on. Take special care putting the pack on at this point if it is fully weighed out (as the straps are loosened). Make sure the pack is centred on your back for an accurate start to the fitting. It may help to lean slightly forward to ensure proper placement of the lumber pad against your back.

(3) Fasten the hip belt. When fastening the belt that the side of the belt are resting on the iliac crest (pelvic bone). This will ensure a good load transfer when walking. A quick way to ensure this fit is to fasten the buckle so that it is resting one and a half to two inches below your superficial facia (belly button).

(4) Position the high spot on the shoulder. This will normally be where the clavical bone meets the shoulder joint. Tighten the shoulder harness straps so that the red flag indicators are at the high point of the shoulder. This will deliver the best top tension strap stabilisation relationship (the relationship is dependent on the angle at which the strap pulls on the shoulder).

(5) Adjust the back length using the size adjusters (along the back system). The object is to bring the shoulder harness into the best contact with your body, whilst keeping the red flag positioned at the top of your shoulder. This will ensure a good fit relationship between the scapular pads, and the lumber pad on your back. It will also help the pack to distribute the load evenly along your back.

(6) Adjust the load balance straps. Take special care to ensure that the straps the tightened enough to help stabilise the balance of the sack, but not so much as they distort the shape of the hip belt or shoulder straps. The lower side stabilisers are responsible for keeping the load in balance with your back during motion, whilst the top tension straps keep the load balance around the top of the pack as even as possible.

(7) Tune, Tune, Tune. Review steps 3 to 6 to gain optimum comfort and fit throughout your activity. The Self Adjust system (SA) allows users the unique ability to change the load transfer throughout their activity. If your shoulders feel tired, loosen the SA to allow the hips to take more weight and vice versa. No other system on the market offers this level of flexibility and comfort, whilst delivering such a high performance load transfer.
