The Basics of Backpacks for Hiking
The seemingly endless variety of backpacks can be mind boggling when trying to choose the right one for you. They come in a range of materials, colors, sizes, and can have any number of extras for the most experienced hiker. In order to find our way through the rain of possibilities, let’s just focus on some basics for now.
Small and Special Purpose Packs
Though many small packs are not backpacks, because they’re not carried on your back, they’re still useful for short hikes. Sometimes referred to as fanny packs or waist packs, they usually have a couple compartments and a single strap. They are great for holding several small items like band-aids, sunscreen, small bottled water, or even snacks like trail mix or nutrition bars.
There are some great special purpose packs that can hold water and include handy tubes for drinking. These types of packs can hold up to a gallon or two of water. Keep in mind though that a gallon of water weighs approximately 8 pounds and traveling light is always a concern while hiking. It is up to you to determine the trade off of weight for water.
Backpacks Classified by Volume
If you are planning a longer hike or you wish to carry more items than a small pack will hold, there are plenty of larger packs to choose from. A backpacks size is expressed in terms of its volume, usually measured in liters. You might think this is a reference to how much liquid a backpack can hold, but it really just refers to how much space is available.
Day Backpacks
Small to medium sized packs, also called day packs, are designed for short hikes. Unlike the small packs mentioned earlier, these packs have shoulder straps to carry them on your back. They may or may not have a belt or chest strap. They range in size from 24 to 36 liters and come in an assortment of styles.
Midrange Backpacks
The size of midrange backpacks, which can also be referred to as midsize or light duty packs, falls in the range of 35 to 70 liters. They usually have a waist belt and shoulder straps with easy clipping buckles. A backpack in this size range can carry quite a bit and is usually made from durable material. You may be tempted to pack a lot of gear in it, but remember you still have to carry it around.
The Largest Backpacks
Sometimes called heavy duty, full-sized and so on, large backpacks have 70 liters of space or more. Needless to say they can carry a lot of gear. In addition to the waist belt and shoulder straps, there are special supports or splines threaded across the back and waist to provide more stability which makes the pack easier to carry.
These backpacks are usually designed to ride higher on your back to prevent pressure on your lower back. This can help your endurance by preventing lower back pain. Heavier loads are easier to carry over time if they are directed onto your shoulders instead of lower down your back. Also, you will probably walk more upright with a higher resting load.
These full size backpacks are made from very sturdy composite materials and are extremely tough. Many can hold sleeping bags and small tents. To handle a lot of weight, large packs have well designed frames made from light weight yet strong aluminum tubing that forms to the body and provides good lumbar support.
The Right Backpack for the Trip
No matter what hiking trip you’re planning, there is a backpack that will fit your needs. You just need to consider how long the trip will be and what essential items you will need to take along. Obviously, full size backpack is too much for a quick day trip, and likewise, you cannot fit a tent in a fanny pack for a multi-day excursion. Only you can make the final decision on what backpack is right for you.
