7 Best Backpacks for Multi-Day Hikes

7 Best Backpacks for Multi-Day Hikes

A backpack is one of the first pieces of gear you’ll need to get started hiking. Considering you’ll be wearing it for a lot of hours at a time, you’ll want to make sure you’re picking the right one. The best backpacks for hiking aren’t cheap but it’s an investment you make to add to your hiking gear list that will last for years.

Fit is a key issue with bigger internal and external frame packs for multi-day hikes and it’s the most important issue you’ll face. It is all about the “suspension system”, which is the part of the pack responsible for bearing the weight and connecting it to your body: the shoulder straps, the hipbelt, the frame, the back padding, and the lumbar area.

Critical Considerations

Trip Length = Volume Capacity

In hiking life, the longer you plan to spend on the trail, the bigger pack you’ll need. Backpacks are sized by how much they can hold (volume) and measured in liters. If you’re planning a trip in winter, you might need more room for extra layers and a warm sleeping bag. Weekend trips (1-3 nights = 35-45 liters), multi-day (3-5 nights = 50-65 liters), long trips (6 nights+ =70 liters+).

Size – Torso Length

In backpacks, torso length matters more than your height. How to measure: Tilt your head forward and have a friend feel along the base of your neck for a bony bump - this is your C7 vertebra in case you wanted to know and the top of your torso length. The bottom of your torso length is at the top of your hip bones. An easy way to find this spot is to put your hands comfortably on your hips; it’s where your thumbs point to on your back. Your torso length is the distance between these two points.

General guide - Extra Small: up to 15 ½”; Small: 16″ to 17½”; Medium/Regular: 18″ to 19½”; Large/Tall: 20″ and up.​


Do not try to cut out weight on the backpack itself. This will usually make the straps dig into the skin. Have a good balance between weight, comfort, and durability.
