Backpacking Packs: Everything You Need to Know

Small backpacks are great for day hikes and travelling but when it comes to staying out in the backcountry for multiple days we need something a bit bigger. It needs to hold our shelter like a tent, sleeping gear, food, water and clothes in a light enough package to carry for days straight.

Backpacking packs, or multi-day packs, are big enough to hold food and gear for a multiple days, sometimes a week or more. They are one of the first things you’ll likely purchase when setting up your backpacking kit.

Buying a Backpacking Pack

Capacity in litres

Every backpack has a size measured in litres. This is how much space is inside. Common sizes for backpacking are 50, 60 or 70 litres but the pack just has to be big enough to hold all your gear. If you have less gear, you can take a smaller pack.

If you are thinking of doing larger trips into the future, like 4-7 days, you’ll probably need a 60 or 70 litre pack. Most packs offer attachment points and webbing on the outside to lash other gear on if it just doesn’t fit inside.

Try to pack everything you need inside. Things fall off the outside, get caught on branches or get more wet than you’d like. Attach items to the outside only when you absolutely have to.

With a bigger pack comes the urge to fill it. You shouldn’t be taking the kitchen sink hiking. Only take the essentials.

Fit

Packs are usually sized based on their length. There will be a small, medium and large or small/medium and large/extra-large. Each manufacturer will have instructions on how to measure the length of your back to see which pack should fit you best.

Once you’ve got the pack size right, you can usually make minor adjustments to the shoulder strap height. This will help you dial in the exact fit you want. Fitting is easier when there’s a bit of weight inside

What you are looking for is to have the middle of the hip belts around your waist sit on the top of your hip bones. With the hip belts on the tops of your hip bones, the shoulder straps should comfortably come up and over your shoulders, staying in contact all the way over.

Once the pack is fitted properly, fill it up the rest of your gear or an equivalent amount of weight. With gear, food and water, packs can weigh 30 to 40 pounds or more. Spend as much time as you can with the pack on before you buy it, and before going on any trips to the backcountry. You don’t want to be in the middle of nowhere and find out the shoulder straps bearing 40 pounds don’t fit properly.

Weight vs Features

There will always be a trade off between weight and features. In a perfect world, we could have a featherweight pack with all the whizbangs and doodads.

Here’s a list of features a pack may have that adds functionality but also adds weight.

  • Shoulder strap and waist belt padding

  • External pockets

  • Webbing and attachment points

  • Included pack cover

  • Internal frame

Always try to get the lightest pack possible with the features you need. You may be happy paying a little extra cost in weight for a bit more padding or more external pockets.

Waterproofing

Most packs are not waterproof. They require some an accessory to make them waterproof. Usually people buy a thin waterproof cover called a pack cover. These need to be the right size for your pack. Sometimes they are included with your pack but often not.

Another option is to put everything in waterproof bags like a garbage bag or drybags inside your pack. The pack will get wet but it won’t matter since everything inside is waterproof.

Pack covers are a bit like rain jackets. Some trips you won’t need to use them at all. Others, you’ll use them the entire time. Backpacking in the Pacific Northwest it’s a requirement any time of the year.

Glossary

Pack Cover – A waterproof cover that covers the whole pack. Rarely comes with the pack and usually comes separately.

Sternum Strap – The small chest-level strap that pulls the shoulder straps together.

Iliac Crest – The top of your hip bones. Waist belts on backpacks should be centered on this one for the most comfortable carry of a bigger pack.
