Field Manual · Sizing
Pick your
size.
The Bushranger Frame comes in six sizes. The right one depends on your torso length and how much weight you intend to carry. When in between two sizes, lean toward the smaller one — the frame should sit snug on your back, not loose around it.

Heights are guidance only. Torso length matters more than total height — measure from the C7 vertebra (base of neck) to the iliac crest (top of hip bone).
How to measure
Two minutes with a soft tape and a friend gets you a more accurate fit than guessing from height alone.
- 01
Stand upright. Tilt your head forward and find the bony bump at the base of your neck — that's the C7 vertebra.
- 02
Place your hands on your hips with thumbs pointing back. Where your thumbs land is the iliac crest.
- 03
Have someone measure the straight-line distance between those two points along your spine.
- 04
Match the measurement to the chart above. Between sizes? Go smaller — better load transfer.
