Camping backpacks come in three main varieties: external-frame packs, internal-fram paks, and day packs.
External-frame camping backpacks: use aluminum tubing to distribute the load. They are often easier to pack, and more forgiving if you don’t pack a load evenly. External-frame camping backpacks are also cooler to carry since the frame puts an inch or so of space between your body and the pack. Plus, external-frame camping backpacks are typically less expensive than internal-frame camping backpacks. Because of the price, and the forgiving load distribution, external-frame camping backpacks are excellent for beginning hikers or campers.
Internal-frame camping backpacks: use stays (flat bars, usually of aluminum or plastic) to distribute the load’s weight. Internal-frame camping backpacks are more flexible than external-frame camping packs, making them more ideal for adventurers like skiers and mountain climbers. The internal-frame camping backpack is also more form-fitting. This means that there will be less of a chance that the bag snags on branches or other obstacles as you’re hiking.
Day Packs: do not have a frame. These are also called rucksacks. The load rests mainly on the shoulders, but some day packs have hip belts to carry some of the load. They are small and light—good for a hike from your base camp, or maybe an overnight camping excursion. They are versatile and are usually less expensive than internal- or external-frame camping backpacks. They are great if you’re car camping and need something for carrying snacks and water during a hike.
Here are some features to think about when buying a camping backpack:
Camping backpack size: Camping bags that are less than 4,000 cubic inches are great for a one- or two-night camping trip. Camping backpacks between 5,000 and 6,000 cubic inches are suited for weeklong camping trips. Remember to buy a camping backpack that’s suited for your kind of backpacking. There’s no sense in getting a bag that is too big, as that’s just extra weight to carry around.
Hip belts: Hip belts are an absolute must for any kind of backpacking. Hip belts distribute some of the bag’s weight to the hips, relieving the shoulders. Hip belts are often padded with foam for more comfort and greater stability.
Detachable pockets: Many camping backpacks have a large top pocket that can be detached to serve as a fanny pack or day pack.
Water bottle holster or hydration pocket: Often camping backpacks come with specialized compartments to keep your water supply easily accessible. Some have large pockets that can accommodate hydration systems
