Backpack fit comes down to matching torso length, not your height, and getting the hip belt to actually carry the weight rather than your shoulders.
- 1
Measure your torso length, not your height
Torso length is measured from the C7 vertebra (the bony bump at the base of your neck) to the point level with your iliac crest (top of your hip bones) — this number, not overall height, determines correct pack size.
- 2
Fit the hip belt first
The hip belt should sit on top of your hip bones, not your waist, and should carry the majority of the pack's weight — a properly fitted hip belt transfers roughly 80% of load off your shoulders.
- 3
Adjust shoulder straps to hug, not dig
Shoulder straps should wrap snugly without gaps at the top, and without digging painfully into your shoulders — they stabilize the pack rather than bear the primary load.
- 4
Set load lifter straps to about 45 degrees
The load lifter straps connecting the top of the shoulder straps to the pack body should sit at roughly a 45-degree angle, pulling the pack's weight closer to your back for better balance.
- 5
Re-check fit with a loaded pack
An empty pack can feel fine even when poorly fitted; always test fit with a realistic loaded weight, since load distribution issues often only become apparent under actual trail weight.
