A well-packed 35-pound pack carries more comfortably than a badly packed 28-pound one. Load position determines whether the weight rides on your skeleton through your hips or hangs off your shoulders pulling you backward.
The system is simple: three vertical zones, heavy things close to your spine at mid-back, and a hip belt doing most of the work.
Fit the pack before you load it
Pack fit is determined by torso length, not height. Measure from the C7 vertebra — the bump at the base of your neck when you tip your head forward — to the top of your iliac crest, the shelf of your hip bones. That measurement, not your shirt size, picks your pack size.
The hip belt should wrap the iliac crest with the padding centered on the bone, not above or below it. Done right, roughly 80% of the load rides on your hips and the shoulder straps merely stabilize.
- ›Load order when putting the pack on: loosen everything, hip belt first, then shoulder straps, then load lifters, then sternum strap.
- ›Load lifters should angle up at about 45 degrees. If they're flat, the torso length is wrong.
- ›Women's-specific packs have shorter torsos and differently curved belts — fit trumps label.
Load in three zones
The bottom zone holds bulky, light, and not-needed-until-camp items: sleeping bag, sleep clothes, and camp shoes. This creates a compressible base and keeps light bulk away from your center of gravity.
The core zone — mid-back, tight against your spine — holds the dense things: food, cookset, water reservoir, bear canister. Heavy weight here sits over your hips and keeps you upright. The top zone holds what you want during the day: rain shell, insulation, first aid, snacks, water filter.
- ›Heavy items away from your spine make you lean forward and destroy your posture.
- ›Fill every gap — socks in the cookpot, stuffing in the corners. Voids let the load shift.
- ›Rain shell always accessible without unpacking. Always.
Use the outside sparingly
Hip belt pockets are for snacks, lip balm, and your phone. Side pockets hold water bottles and a tent's pole set. The lid pocket takes maps, headlamp, and a small kit.
Beyond that, resist strapping things on. Dangling gear snags on brush, throws off your balance, and gets soaked. The classic exception is a wet tent fly, which is better outside than soaking everything inside.
- ›Anything strapped outside needs two attachment points or it will swing.
- ›Trekking poles go in dedicated loops, tips down, when you're scrambling.
- ›Cinch all compression straps after loading — a loose pack sways with every step.
Manage total weight
Base weight is everything in your pack except food, water, and fuel. Under 20 pounds is comfortable, 12 to 15 is lightweight, and under 10 is ultralight territory. Consumables add roughly 1.5 to 2 pounds of food per person per day plus about 2 pounds per liter of water.
A common target is a loaded pack around 20% of body weight, and no more than 25% for most people. If you're over, weigh every item — the savings are almost always in the big three (pack, shelter, sleep system) and in the pile of small things you brought 'just in case'.
- ›Water is the heaviest thing you carry. Know where the sources are and don't over-carry.
- ›Repackage food out of retail boxes; you can lose a pound of packaging on a weekend.
- ›Keep a gear list with weights. You cannot cut what you don't measure.
Waterproof from the inside
Pack covers help but leak at the seams, blow around in wind, and do nothing about water running down your back into the top of the pack. The reliable approach is a waterproof liner — a heavy-duty trash compactor bag or a purpose-made pack liner — inside the pack.
Inside that liner, keep the truly critical items — sleeping bag, insulation, sleep clothes — in their own dry bags. Redundancy is what keeps you from a genuinely dangerous night with a soaked bag.
- ›A trash compactor bag weighs two ounces and outperforms most rain covers.
- ›Color-code dry bags so you can find things by feel in the dark.
- ›Electronics and first aid in a separate small dry bag, always.

Frequently asked questions
How much should my pack weigh?+
Aim for a loaded pack around 20% of body weight and no more than 25%. A base weight under 20 pounds makes almost any trip pleasant.
Where should heavy items go?+
Mid-back, tight against your spine, roughly level with your shoulder blades. That puts the weight over your hips instead of pulling you backward.
What size pack do I need?+
Weekend trips: 40–50L. Three to five nights: 50–65L. A week or more, or winter: 65L+. Buy for the trips you actually take, not the longest one you imagine.
Rain cover or pack liner?+
Liner. Covers leak at seams and let water run down your back into the pack. A trash compactor bag inside the pack costs two dollars and works better.
