How to Pack a Backpacking Bag | Load It Right, Hike Easier

Pack heavy items close to your back and centered, with light bulky gear at the bottom, to keep the load stable.

How you load your pack changes how it feels on your body. A properly packed bag puts weight where your hips and spine handle it best, so you’re not fighting your gear with every step. It takes about ten minutes once you know the order.

The Classic Bottom-To-Top Packing Order

The standard method that REI and other outfitters teach works for nearly every internal-frame pack. Start with everything spread out on the ground. Leave behind anything you won’t use — the easiest way to lighten up. Then load in this order:

1. Sleeping bag first. Place it in the bottom compartment or as the lowest layer — it’s bulky, light, and you won’t need it until camp. Compress it fully and slide it in vertically if your pack has a bottom compartment, or horizontally if it doesn’t.
2. Heavy gear against your back. Dense items like your stove, fuel, cookware, and heavy food belong in this core zone, centered between your shoulder blades, to keep heaviest weight close to your center of gravity.
3. Structured items placed with care. Slide tent poles along the side in a sleeve if available, or strap them outside. A foam pad can wrap around the inside wall to create a cylinder that holds smaller items — avoid bulges that poke into your back.
4. Lighter, clothing layers and soft items on top. Items you need at day’s end — a puffy jacket, camp clothes, extra socks — go near the very top. The tent fly can sit here too.
5. Day-use items in pockets and the top lid. Snacks, navigation, a headlamp, sunscreen, and a first-aid kit belong in the top compartment or exterior pockets for easy grab.

Once everything is in, tighten the side compression straps to pull the load together, stop gear from shifting, and make the pack feel streamlined.

Weight Zones And What Belongs Where

If you remember one thing: heavy stays close to your spine, light stays far from it. Packing soft items against your back is a common mistake that pulls you backward. REI’s experts use a specific zone system:

• Core (middle, against the back): stove and fuel, cookware, water or a bladder, dense food
• Bottom: sleeping bag, sleep pad, camp-only gear
• Top / pockets: snacks, navigation, first-aid kit, headlamp, rain shell

A bear canister goes in the core zone — it’s heavy and rigid. An Ursack or soft-sided bear-resistant bag is easier to fit. Check local regulations before hiking.

Getting The Fit Right Matters More Than The Packing

No amount of careful loading can fix a pack that doesn’t fit. Fit depends on torso length, measured from the base of your neck to your hip bones, not height. Most adults fall between 15 and 22 inches. Check the brand’s sizing chart and adjust shoulder straps, load-lifter straps, and hip belt.

If over that, cut items before reorganizing.

What Actually Stays Dry And What Doesn’t

Waterproofing is critical for a down sleeping bag — once wet, it loses nearly all insulating power. The same goes for dry clothes and electronics. Use a pack liner, dry bags, or heavy-duty resealable bags, or line the pack with a trash bag as a simple rain barrier. Keep stove fuel separate from food and tent materials to prevent leaks from soaking your meals or shelter.

External-frame packs are the exception — they may require lashing items outside. Even then, keep outside carry minimal; it throws off balance and snags on branches. REI’s detailed guidance on loading a backpack properly covers the zone method in full.

Before heading out, do a final check: adjust load-lifter straps to angle back slightly, cinch the hip belt snugly over your hip bones, and ensure nothing pokes your lower back. Still choosing a pack? See our roundup of the best travel backpack bags for every trip.
