The anatomy of a backpack
Understanding the common features of a backpack can help you to understand what you require from your new bag. Rucksacks and backpacks features can range from basic to packed with features and our anatomy guide will help you decide what you need.
Material – The material of your bag is about personal preference and use. Heavy duty backpacks are generally made with a strong nylon material that withstands abrasion and varying temperatures. Also popular is the polyester outer, durable and wear-resistant; it doesn't wrinkle as easily and is more lightweight than nylon. For a more stylish finish, choose leather or suede – with the same durable properties but also requiring a little more care and attention.
Access – Most backpacks are designed with top access so you can reach into the main compartment from the top of the bag. For travelling and longer trips, front access can be more practical so you can open the main compartment fully from the front making packing easier. Finally larger rucksacks often feature side or base access to the main compartment that is easy to use and can prevent theft if you’re out and about.
Shoulder straps – The larger your bag, the better your shoulder strap needs to be. Padding on straps is paired with a wider surface area to prevent the straps from digging into your shoulders. In smaller bags that will hold less, thinner straps offer more flexibility and mesh straps are great for ventilation.
Back panel – Padded and contoured to provide comfort hour after hour, backpack back panels come in a range of styles. Look out for adjustable panels so you can customise your fit for the perfect shape. Added foam provides cushioning and mesh adds breathability to prevent overheating.
Frames – Rucksacks are created with both internal and external frames that help to transfer the weight of your bag evenly. But what is the difference?
Internal frames are often made from steel, but more technical packs are designed with aluminium or carbon fibre which is more lightweight.
External frames are usually used in larger capacity bags and come in a range of shapes. Usually made from lightweight aluminium they’re available in straight frame shapes that aid ventilation between the bag and the wearer, S-shapes designed to contour to the wearer and hip frames that transfer weight to the legs for added comfort.
Pockets – Designed on both the inner and outer of backpacks to help organise your gear, pockets are an essential feature of any good bag. Inner pockets are essential for smaller items, while top, front and side zipped pockets are great for keeping items at hand while you walk. Side mesh pockets are most commonly used for drinks bottles and bellows and side pockets are collapsible, meaning they can be packed away when you’re not using them.
