A hiking backpack is only as good as its fit and how it is packed. The most expensive pack rides badly if it is the wrong torso length or loaded in the wrong order, and a modest pack carries beautifully when both are right. This hub covers measuring, sizing, adjusting, and packing a pack correctly.
Torso length, not height, sizes a pack — measured from the C7 vertebra at the base of the neck to the iliac-crest line at the hips. The hipbelt should carry about 80% of the load, and a loaded pack is adjusted in order: hipbelt, shoulder straps, load lifters, then sternum strap. The measuring and adjusting sub-hubs below walk through each step precisely.
Pack in zones — sleep gear low, dense items against the spine at mid-height, quick-access items up top — so the load stays balanced. Aim for a loaded weight near 20% of body weight, and track base weight (everything but food, water, and fuel) if you want to go lighter. The packing and weight guides here connect directly to the capacity hub, because how you pack changes the liters you need.
