Hiking Backpacks 101
Hiking backpacks come in a huge variety of sizes, colors and fabrics – in fact there’re as many backpacks on the market today as there are trails to use them.
To help you navigate through this multitude of choices, let’s start with some backpack basics.
The smaller packs like waist or fanny packs are not technically backpacks – simply because they’re not worn on the back. However, they do carry out a similar role but on a small scale - so for short hikes can be perfectly adequate.
For example, a smaller pack with two or three compartments can be used to carry items like a water bottle, snack bars, sunscreen, insect repellant, band-aids, pocket knife and a bunch of other small items.
Daypacks, as the name indicates, are designed to be used for relatively short hikes. They are anywhere from 700 cu. in. to 2,100 cu. in. (12 to 36 liters) in volume and come in a variety of styles. Some have no belt strap while others do have a chest strap to keep the backpack stable. All will have shoulder straps so they can be carried on your back.
Some even have small, special purpose water bladders with tubes and other gadgets for drinking. They’re often called hydration packs and can hold one or two gallons. Remember though that a gallon of water weighs about 8lbs (3.6kg).
Whatever the size of your hiking pack, the trick is not to try to put too much in them. So when you plan to be out longer, or need to carry more, you should use a larger pack rather than stuff too much into a small daypack. There are a wide variety of larger packs to choose from. They’re usually categorized by size, typically the volume measured in cubic inches or liters. A liter is just over a quart in volume, but here it refers to space, not the quantity of liquid something holds.
Larger packs that range in size from around 2,100 cu. in. to 42,000 cu. in. (35 to 70 liters), are called a number of different names - midsize, midrange, light duty packs and others. When utilized properly they can hold quite a large quantity of gear, which makes it tempting to pack too much. Remember, you have to carry the pack and the contents!

This category of backpack is typically made with really sturdy material and they come in a variety of shoulder strap and waist belt styles. These days most will have the sort of plastic ‘dog-leash’ clipping buckles that are so common now.
Heavy Duty Packs
The largest packs also go by an assortment of names - full-sized, expedition, heavy duty and so on. They’re the ones that are over 42,000 cu.in (70 liters), can carry plenty of gear and have a number of special features to facilitate this.
Special splines or supports are often threaded through the shoulder straps, across the back or waist and otherwise. These stiffer elements help stabilize the pack, making it more comfortable to carry. They are often designed to ride higher on the back so as to keep the load off the lower back, which helps greatly to reduce fatigue and prevent back pain.
These heavy duty packs provide all manner of lumbar support, pads, special materials and well-engineered balance mechanisms. The frames have aluminum tubing in a form that has been scientifically designed. Many have special holders for sleeping bags, or even a small fold-up tent. They come in ultra-sturdy composite materials and are close to indestructible.
Unfortunately the human body is not, so bear in mind that you have to lug all that gear around. Make sure you’re only carrying what you’ll really need, no more, no less.
