How To Choose The Right Sized Backpack For You
Since we know how important it is to find the right size of the backpack, we should consider some factors before choosing the right one among hundreds of backpacks available in the market.
Many styles and designs offer various features and making a decision can be confusing sometimes. That is why there are some factors listed below so that the process of choosing becomes easier.
Your Body Type
Before choosing the perfect bag, you need to understand what your body type is and how long your torso is. So it is required to make sure that the back fits with your torso, and to that, you need to measure your length, hip size and try to adjust the length of your torso with the backpack.
Measure Your Torso Length
Bend down, and you will notice a bump behind your neck. It is known as the cervical vertebra, and from there, the gap of the backpack starts and determines the upper torso. Make sure to measure the length between the neck and the shoulders.
Measure Your Hip Size
Here all you need to do is, measure the length of your hip that is you measure the tape around the hip. This is important because most of the weight( almost 70 to 80 percent of weight) lies on the hip and that is why understanding the perfect fit is required.
Adjusting Torso Length
This time you will need help from your friend. It would be best to ask any of your friends to calculate the gap of the back to determine the length of the torso.
You need to keep one thing in mind: how much weight can you generally carry while hiking? This also determines the limit of your ability to carry. You should carry a bag which helps to distribute the weight evenly.
Different backpacks serve different purposes depending on the weather. Trekking and long trips include getting wet during the rainy season or hiking during winter. Fabric plays an important role as they need to protect from the sunlight or extremely cold weather.
