Karrimor SF SA Back System Fitting Guide
| The Karrimor SF SA Back System is a design feature incorporated into some backpacks and rucksacks produced by Karrimor SF. This system is designed to provide users with a comfortable and supportive fit, particularly during extended periods of wear. Ensuring the perfect fit of your backpack is crucial for comfort during any adventure, and the Karrimor SF SA Back System ensures just that. By starting with all straps loosened, users can easily attain the maximum size, providing a customisable starting point for a tailored fit. As they put on the rucksack, careful attention to centering it on the back guarantees an accurate fitting process. This initial step, combined with a slight forward lean to position the lumbar pad correctly, sets the stage for optimal comfort and support. Fastening the hip belt securely onto the iliac crest (pelvic bone) ensures not only comfort but also effective load transfer while walking. This strategic placement, coupled with the guidance to fasten the buckle just below the belly button, enhances stability and balance during use. Moreover, adjusting the shoulder harness to position the high spot accurately on the shoulder joint maximises top tension strap stabilisation, providing further support and preventing discomfort during prolonged wear. With these adjustments, users can expect a personalised fit that minimises strain and allows for unrestricted movement, ensuring an enjoyable and hassle-free outdoor experience. Having a backpack that is correctly fitted is paramount for minimising fatigue during outdoor activities. A properly fitted backpack ensures that weight is distributed evenly across the body, reducing strain on any one area. When the weight is evenly distributed, muscles are less likely to become fatigued quickly, allowing for longer periods of comfortable wear. Additionally, a well-fitted backpack prevents unnecessary movement and bouncing, which can lead to muscle fatigue and soreness over time.

SA Back System Fitting Guide |

(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 ensure that the side of the belt is 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.
