Planning to buy a new pack for backpacking? There are three main areas where you’ll need to make choices.

Backpack capacity: The size of the pack you’ll need is tied to the length of your trip and how much weight and bulk you want to carry.
Backpack features: These are the refinements that affect how the pack works for you.
Backpack fit: Torso length—not your height—matters most.

Types of Backpacks
types of backpacks
Weekend (1-3 nights; 30-50 liters)
Efficient packers using newer, less-bulky gear can really keep things light on 1- to 3-night trips by using a pack in this range. Be aware that packing light requires self-discipline and careful planning. If you can pull it off, though, the light-on-your-feet rewards are fantastic. Shop weekend packs.

Multiday (3-5 nights; 50-80 liters)
These are the most popular backpacking packs sold at REI and they’re an excellent choice for warm-weather trips lasting 3 or more days. Packs in the 50- to 80-liter range are also great for shorter trips where you pack a little more luxuriously or multisport activities like backcountry skiing. Shop multiday packs.

Extended-trip (5+ nights; 70 liters or larger)
Trips of 5 days or more usually call for packs of 70 liters or more. These are also usually the preferred choice for winter treks lasting more than 1 night. (Larger packs can more comfortably accommodate extra clothing, a warmer sleeping bag and a 4-season tent, which typically includes extra poles.) They’re also a good option for folks taking young children backpacking because Mom and Dad wind up carrying a lot of kids’ gear. Shop extended-trip packs.
