Features of backpacks/Rucksacks

Here is the list of 15 backpack features that should be present in your bag based on the activity and equipment/gear you are carrying:

1. Backpack frame:

There are mainly 3 types of rucksacks based on the frame

i) Frameless backpacks:

These type of bags come with no frame support. Frameless backpacks generally have low capacity and can be used for day trip activities or for lightweight travel. There are also backpacks in which you can remove the frame to reduce the weight.


ii) Internal frame backpacks:

These backpacks have frames embedded which are not visible from outside. Rucksacks with internal frames provide better stability and generally are lightweight. The internal frame includes metal strips, metal frames, or lightweight hard plain material.


iii) External frame backpacks:

These types of backpacks have frames visible from the outside. They are heavy as compared to internal frames but allow proper vertical load transfer to the hips. The gap between the bag and body due to external frame improves the ventilation.


2. Adjustable back system

This helps to adjust the distance between the shoulder straps and hip belt to fit the backpack according to your torso length. The adjustable backpack system adds a little weight to the rucksack.


3. Backpack Openings

There are generally 3 types of openings present in the backpacks:

i) Top Loading

Most of the backpacks have top loading system which allows access to your items from the top. In these types of bags, you need to keep the items deep in the rucksack which are not required frequently.

ii) Front Openings

Large packs provide zippered access from the front to access the items in the bottom or deeper of the rucksack.

This base opening allows you to reach the items present in the bottom of the pack. Some backpacks provide separate section at the bottom of the rucksack which can be accessed using this base opening.


4. Top Lid / Detachable Bag

Some bags have a pocket of size around 10-25 litre or detachable bag on the top main bag. These small bags are ideal for short trip around your camping location when you do not wish to carry the entire load.

5. Expandable bag section

Some bags have an expandable section around the top opening that allows users to increase the height of the bag and hence the storage capacity of the bag.

iii) Sternum Strap

This is a backpack chest strap which connects shoulder straps and reduces the jarring of the backpack.

iv) Hip Belt/strap

This strap helps to reduce the weight from the shoulder by transferring most of the rucksack weight to your hips. This belt with padding and pockets should fit properly on the top of your hip bones.
