How to Pack a Backpack

I learned this the hard way in the Rockies: if your backpack is packed badly, even a short hike feels brutal.
On one early overnight trip in Kananaskis, I had my stove, food, and water all stuffed at the bottom, my sleeping bag jammed in the middle, and my rain jacket buried somewhere I couldn’t find. Two hours in, my lower back was screaming and the pack kept pulling me backward on every incline. Nothing was technically wrong with my gear. The packing was the problem.
Once you understand where things should go, backpacking gets way more comfortable. Here’s the method I use now for every overnight trip.
Before You Pack: Lay Everything Out
Don’t start stuffing random gear into your bag. Lay it all out first so you can see what you’re bringing.
I split everything into five piles:
- Sleep system (bag/quilt, pad, sleep clothes)
- Shelter (tent, stakes, footprint)
- Kitchen + food (stove, fuel, meals, water filter)
- Trail essentials (first aid, rain gear, map, headlamp, sunscreen)
- Worn items (layers, shoes, poles)
This takes five minutes and stops you from forgetting something obvious like your spoon or headlamp.
Choose the Right Pack Size
For most beginners doing 1-3 nights, a 50-65L pack is the sweet spot.
- Under 50L can work if you’re experienced and have compact gear.
- Over 65L usually encourages overpacking.
If you’re unsure, go slightly smaller. A giant pack is a trap because you’ll fill empty space with “just in case” items you’ll never use.
Also: fit matters more than brand. A perfectly packed bag that doesn’t fit your torso will still feel awful.
The 4-Zone Packing System
Think of your pack like a building with four floors.
Zone 1: Bottom (bulky, soft, camp-only gear)
Put your sleeping bag/quilt, sleep clothes, and sometimes your sleeping pad here.
Why: these are soft and light, and you won’t need them until camp.
If your sleeping bag isn’t in a dry bag already, use a pack liner or waterproof stuff sack. A wet sleeping bag is one of the fastest ways to ruin a trip.
Zone 2: Middle, close to your back (heaviest gear)
This is the money zone. Put dense/heavy items here:
- Food bag
- Stove + fuel
- Water reservoir or full water bottles
- Tent body (if wet, keep it separate)
Why: keeping weight centered and close to your spine gives you better balance and less shoulder strain.
If heavy items sit too low or too far from your back, the pack will feel like it’s dragging you backward.
Zone 3: Front/sides of main compartment (medium and soft items)
Use this space to stabilize everything:
- Extra layers
- Rain pants
- Toiletry kit
- Camp sandals (if you bring them)
Think of these as “fill” items that stop the heavy core from shifting.
Zone 4: Top + brain pocket (quick-access items)
Anything you might need during the day goes here:
- Rain jacket
- First aid kit
- Headlamp
- Water filter
- Snacks/lunch
- Map/compass
- Sunscreen/bug spray
- Toilet kit
If you have to unpack half your bag every time it rains, your system is broken.
What Goes in Outer Pockets
Outer pockets are for items you grab constantly:
- Side pockets: water bottles
- Front shove-it pocket: wet rain shell, microspikes, or water filter
- Hip belt pockets: snacks, lip balm, small sunscreen, phone
I keep one “walking snacks” pocket and one “small essentials” pocket. Same setup every trip, so I can find things without thinking.
Weight and Balance Rules
Simple guidelines that actually help:
- Target pack weight: around 20-25% of body weight for beginners
- Keep heavy gear centered: middle/back area
- Keep top light: avoid top-heavy wobble
- Compress your load: use side straps so contents don’t shift
If your pack sways when you turn, it’s not compressed enough.
Water Strategy (Most People Overcarry)
Water is heavy: 1 liter = 1 kg (2.2 lb).
Beginners often carry way too much from the trailhead. Better approach:
- Carry enough to reach your first reliable source.
- Filter along the way.
- Top up before dry sections.
This can cut 2-4 kg from your starting weight instantly.
Pack Fitting: 90 Seconds That Matter
After packing, put the bag on and adjust in this order:
- Hip belt first (should take most of the load)
- Shoulder straps (snug, not crushing)
- Load lifters (light tension)
- Sternum strap (just enough to stabilize)
If your shoulders hurt early, your hip belt probably isn’t carrying enough weight.
Common Packing Mistakes
I still see these all the time:
- Rain gear buried deep
- All heavy items at bottom
- Random loose items instead of grouped kits
- No system between trips (everything moves every time)
- Packing by “what fits” instead of “what I’ll need when”
The fix is consistency. Keep the same item categories in the same places each trip.
My Basic Overnight Packing Template
If you want a quick starter system:
- Bottom: sleeping bag, sleep clothes
- Core near back: food, stove, fuel, tent body
- Around core: puffy, spare layers, toiletries
- Top/brain: rain jacket, filter, first aid, headlamp, toilet kit, snacks
- Outside: water bottles, poles, wet gear
Do this a few times and you’ll dial it in fast.
Final Thought
Backpacking comfort isn’t just about buying lighter gear. It’s about loading what you already own in the right places.
If your current setup feels miserable, don’t start by spending $400 on a new pack. Start by repacking the one you have. One good packing system can make an average kit feel great on trail.
