A backpack is essential if you are planning on hiking. It carries everything you need for a day in the hills or mountains, so it can literally be a lifesaver if something goes wrong.
But a badly fitting rucksack can leave you with a sore back, bruised hips or rubbed skin on your shoulders. It can also make you feel unstable as you walk.
We spoke to Adam Alder-Cox, product specialist at Osprey, which produces the best-selling backpacks in the UK.
He told Saga Magazine that it’s easy to adjust rucksacks, but important to get it right.
“The size and fit of your pack ensures optimal performance and comfort.
"From back length to harness shape and weight distribution, sizing and fit is an integral part of wearing your pack comfortably."
“Sizing and fit are also necessary to ensure that you use the full potential of your pack. Both allow your pack to distribute weight throughout the body and, in turn, provide the best possible comfort.
The size affects the back length, harness and hip-belt of your pack, while the fit adjusts these aspects to meet the dimensions of your body.”
Start by adding a little weight to your pack. It doesn’t have to weigh exactly what it would for your chosen activity, but the closer it is to real life, the better the fit. Carefully lift the pack on to your back from your knees, and then follow the steps below.
Many rucksacks feature an adjustable torso length. These allow you to slide the harness up or down to perfectly fit your back length. You can guess the right length for your back to begin with.
Now check to see that there is no gap between your back and the pack. If there is a gap then tweak the back length.
Once the pack is comfortably on your back, the first attachment point is the hip belt strap. It is essential that this is adjusted first, as it distributes the weight evenly between the legs and lower lumbar rather than the weaker points like the shoulders and arms.
Try to position the hip-belt over the upper half of your pelvis bone for maximum comfort.
Next, the harness straps need to be pulled downwards so that the webbing is comfortably tight, much like the laces on your shoes.
The harness should not impede breathing or be too tight around the collar bone area.
Load lifters (the straps that connect the upper part of the main pack to the shoulder straps) should be pulled forward so that the pack runs straight up and down your back.
The close centre of gravity will allow weight to flow directly down to the ground. The optimum angle for load lifters is around 45-degrees – this will ensure that the pack is straight down your back.
Lastly, fastening the strap across the chest (called the sternum strap) pulls the harness into the chest and away from areas containing lots of blood vessels and nerves.
If the harness is too tight, it’ll restrict breathing, but if the sternum strap is too loose then you can end up with tingly or numb fingers.
Remember, each person’s body is different, so you might need to experiment with adjustments to find the most comfortable fit for you. Taking time to fit your backpack properly really makes a difference and if you aren’t sure, go to an outdoor shop – such as Cotswold Outdoor, Go Outdoors or Ellis Brigham – to get one fitted for you.
Once you've mastered how to fit a backpack correctly, the next task is to make sure the weight inside the backpack is evenly distributed. Points to think about include:
Heavier items should be placed closer to your back, and lighter items should be towards the top and bottom. Keeping the weight closer to your body helps with balance.
Use the compression straps on the sides of the backpack to cinch down and stabilise the load. This prevents the contents from shifting while you’re moving.
After fitting the backpack, perform some arm and upper body movements to ensure the shoulder straps and hip-belt don’t hinder your mobility.
Take a short walk or hike with the loaded backpack to assess the fit. If you experience discomfort or notice any pressure points, readjust the straps and the distribution of the pack’s contents.
Which backpack is for you?
There is a huge range of hiking backpacks on offer, including ones to suit longer backs and those with a bigger build, as well as options specifically tailored to a woman’s frame.
Before buying one, it’s worth doing your research to find the one most suitable for you. Popular brands include Rab and Lowe Alpine, Gregory and Berghaus.
Catherine Quinn, president of the British Chiropractic Association, says a badly fitting backpack can cause issues.
She says: “Walking offers enormous benefits for physical and mental wellbeing, so feeling confident that you will enjoy that walk in comfort and then be able to repeat it is so important.
"The weight of a heavy backpack can cause a walker to lean forward to compensate for the backward pull. The posture is compromised as the neck is extended, and pressure is put on the hips and lower back, which can cause pain in all of these areas.
“That’s why it’s so important to correctly adjust your backpack.”
