Most people pack a backpack the same way they load a car: heaviest things first, whatever fits goes wherever it fits. After enough days on trail where your back is screaming by mile 6 or you're digging through everything to find your rain jacket, you learn there's a better way.
This is how we pack for multi-day backcountry trips — from overnight Enchantments permits to 10-day circuits in Patagonia. It took a few painful trips to get the system right.
The Three Zones of a Backpack
Proper pack loading is about weight distribution relative to your center of gravity. Think in three vertical zones:
- Bottom zone: Sleeping bag, sleeping pad (if internal), soft items you won't need until camp. Light but bulky.
- Core zone (against your back, mid-pack): Heaviest items — tent body, bear canister, food bag, water. As close to your spine as possible, between shoulder blades and hips.
- Top zone: Rain gear, first aid kit, snacks, anything you need to access quickly without stopping.
Hip Belt vs Shoulder Straps: Where the Weight Should Sit
A properly fitted, properly loaded pack should carry 70–80% of its weight on your hip belt — not your shoulders. Your shoulders stabilize and balance; your hips carry. If you're feeling pack weight primarily in your shoulders, the issue is almost always one of two things: the pack isn't fitted to your torso length, or the heavy items are packed too low.
Fit the hip belt first before adjusting shoulder straps. The hip belt padding should sit centered on your iliac crest (the top of your hip bones). Tighten it fully, then draw in the shoulder straps just until the pack lifts slightly off your hips — not to take weight off, just to stabilize the load.
What Goes in the Hip Belt Pockets
This is underused real estate on most packs. Phone, sunscreen, lip balm, snacks for the next hour, emergency contact card. These are the things you want without stopping and taking off your pack. Don't waste hip belt pockets on items you won't touch until camp.
External Attachment: What Works and What Doesn't
Trekking poles, wet items, a foam sleeping pad — these all go external. But keep external attachments low and symmetrical. High external loads raise your center of gravity and make the pack feel unstable on technical terrain. A soaking wet rain jacket strapped to the top of your pack is fine; a 2-pound item strapped there for convenience is a balance problem.
The Full Packing Sequence
- Start with a pack liner (garbage bag or dedicated liner) inside the main compartment.
- Load the sleeping bag compressed into the bottom.
- If your pad is internal, roll it around the inside perimeter as a frame.
- Pack your tent body and poles along the back panel — this is your heaviest structural item.
- Fill in around the tent with your food bag and bear canister, pressed against your back.
- Clothes, cook kit, and fuel fill the remaining space around the heavy core.
- Rain gear, first aid, snacks go in the top lid or brain.
- Wet gear and trekking poles attach externally.
- Close the pack liner, then the main compartment.
- Cinch compression straps to stabilize the load.
Weight Targets by Trip Length
Base weight (everything except food and water) is the number worth obsessing over. A reasonable target for most backpackers:
- Ultralight: Under 10 lbs base weight. Achievable but requires significant gear investment.
- Lightweight: 10–15 lbs. The sweet spot for most experienced backpackers.
- Traditional: 15–25 lbs. Fine for short trips and car-camping-adjacent experiences.
- Heavy: Over 25 lbs base. Start cutting before your knees do.
Your total pack weight (base + food + water) will typically run 5–15 lbs higher than base weight depending on trip length. On the Enchantments, we start day 1 around 32–34 lbs total. By day 3 it's under 25.
