In plain English

A hiking backpack has several straps, and the order you tighten them in matters. Think of it like building a stack of blocks. The bottom block is the hip belt, the padded strap that buckles around your hips. Everything else rests on it.

Buckle the hip belt first so its padding sits on the bony tops of your hips. Then pull the shoulder straps just snug. After that, the small straps above your shoulders, called load lifters, tip the top of the pack toward you. The chest strap, which clips across your chest, keeps the shoulder straps from sliding outward. Last come the small straps on the sides of the hip belt, which pull the pack in close.

Your hips are much better at carrying weight than your shoulders. If you tighten the shoulder straps first, the pack hangs from your shoulders and ends up feeling heavier. Going in order keeps the weight low and steady.

How to Adjust a Hiking Backpack (In Order) — demonstrated step by step, hands and gear only

Adjusting a hiking backpack in the correct order — hipbelt, shoulder straps, load-lifter straps, sternum strap, then hipbelt stabilizer straps — is what makes a loaded pack ride on the hips instead of the shoulders. Each strap sets up the one after it, so working through the sequence in order matters as much as getting any single strap's tension right.

What is the correct order to adjust backpack straps?

The correct order is hipbelt first, then shoulder straps, then load-lifter straps, then the sternum strap, then hipbelt stabilizer straps last. This sequence moves from the strap that carries the most weight to the ones that fine-tune stability, and reversing any step forces the straps after it to compensate for a foundation that isn't set correctly yet.

Working out of order is the most common fitting mistake. A hiker who tightens shoulder straps before buckling the hipbelt pulls the pack's weight upward, and no later adjustment to the load lifters or sternum strap fully undoes that. Starting at the hipbelt every time, even for small mid-hike readjustments, keeps the fit consistent.

How do you adjust the hipbelt first?

Buckle the hipbelt so the padded wings sit centered over the iliac crest — the bony ridge at the top of the pelvis — then pull the straps snug while standing upright, aiming for snug without restricting your breathing. The hipbelt should carry the bulk of a loaded pack's weight on a framed pack, so this step sets the base every other strap builds on.

A hipbelt positioned too high rides on the ribs and doesn't transfer weight to the skeleton; positioned too low, it slides onto the widest part of the hips and loses grip. Both cases usually trace back to the wrong torso length for that pack, which is worth checking before assuming the belt itself is at fault.

How do you adjust shoulder straps after the hipbelt?

With the hipbelt buckled and tightened first, pull the shoulder straps until they sit flush against the shoulders with no visible gap, but without lifting the pack's weight off the hipbelt in the process. The shoulder straps' job at this stage is to stabilize the pack and keep it close to the back, not to bear the load.

A useful check: after tightening the shoulder straps, the hipbelt should still feel like it's carrying the pack's weight. If the pack noticeably lifts or the hipbelt loosens its grip when the shoulder straps are tightened, they've been pulled too far and are taking over work that belongs to the hipbelt.

How do you adjust load-lifter straps?

Pull the load-lifter straps until they form roughly a 45-degree angle between the top of the shoulder straps and their anchor point higher on the pack body, drawing the load toward the shoulders without lifting it off the hips. This step comes after the hipbelt and shoulder straps are both set, never before.

Too steep (near vertical): lifts the pack off the hipbelt and shifts weight back onto the shoulders.
Too loose (near flat): lets the top of the pack lean away from the back, pulling the center of gravity backward.
Roughly 45 degrees: keeps the load close to the spine while leaving the hipbelt in charge of carrying weight.

How do you adjust the sternum strap?

Slide the sternum strap to a comfortable height across the upper chest on its height track, then buckle and tighten just enough to stop the shoulder straps from sliding outward, without restricting the chest. It's adjusted after the load lifters, as the last strap in the sequence before hipbelt stabilizer straps.

Too tight, a sternum strap compresses the ribcage and shortens breath on climbs; too loose, it does little to keep the shoulder straps aligned on the shoulders during arm swing. Light tension is the target, not maximum tension.

What do hipbelt stabilizer straps do?

Hipbelt stabilizer straps, found on the sides of the hipbelt wings, pull the load closer to the body and reduce side-to-side sway once every other strap is already set correctly. They're the final adjustment because they only fine-tune a fit that's already correctly distributed between hips and shoulders — cinching them before the hipbelt and shoulder straps are set doesn't fix a poor base fit, it just pulls a poorly positioned load tighter against the body.

Frequently Asked Questions

A quick check each time is worth it, since padding compresses and clothing layers change between hikes. A full re-fit from scratch usually isn't necessary once torso length and hipbelt size are confirmed correct for your body.

The order stays the same, but load lifters and the hipbelt do less work on a frameless pack since there's no frame to route weight to the hips. Shoulder straps end up carrying more of the load regardless of adjustment on these packs.

How much the hipbelt really carries: the numbers disagree

Fit guides usually say a good hipbelt carries most of the load, but the exact share depends on who you ask. Big Agnes aims for about 80% on the hips,² Alpkit says a correctly fitted belt transfers 60 to 80% to the hips and legs,³ and Kelty says only that most of the load should be on the hips rather than the shoulders.⁵ The US Army's foot-march manual, working with heavy military loads on a frame and hip belt, puts it at about 30% on the hips and lower back and 70% on the shoulders.⁶

These figures are not measured the same way, so there is no single correct number. What the evidence does agree on is direction. In a lab study of load carriage, the hip region tolerated pack pressure significantly better than the shoulder region, static strap force predicted discomfort, and the authors recommend shifting load from shoulders to hips wherever possible.⁴ That is the real reason the hipbelt goes first.

Checking the hipbelt: what makers actually measure

A two-finger gap is a common rule of thumb in some guides, but it is not something the brands in this site's library specify, so this page asks only that the belt stay put and allow full breathing. The checks they do give are different. Deuter says to center the hip fins over the top of the hip bone before securing the belt.¹ Osprey says a correctly sized hipbelt leaves a 3 to 6 inch gap between the tips of the hip pads when tightened, measured at the iliac crest,⁷ and Granite Gear likewise says a properly sized belt leaves a gap in the padding at the front.⁸

If the pad tips meet or overlap when you tighten, the belt is too big for your hips; if the gap is very wide, the padding may not wrap far enough around to grip. Either case points to a hipbelt size problem that strap adjustment can't fully solve.

Load lifters and the sternum strap: ranges, not exact settings

This page uses 45 degrees for load lifters, which matches Big Agnes.² Deuter says the straps work best between 30 and 45 degrees,¹ and Alpkit gives 25 to 45 degrees from horizontal.³ The angle you actually get depends mostly on whether the torso size is right, so a lifter that can't reach a reasonable angle is often a sign of the wrong size. Gossamer Gear notes that straps set too high pinch the neck, while straps set too low reduce weight transfer to the hip belt.⁹

Some guides put the sternum strap one to two inches below the collarbone, while this page just says a comfortable height across the upper chest. The sourced guidance is fairly consistent: Big Agnes says just below the collarbone, lying flat with moderate tension,² and Alpkit says about an inch below.³ Deuter adds that the sternum height is set after the back length is correct.¹ In all cases the goal is the same light tension the page describes.
