the mesh back panel. The recommended arch is about 2.5" (6 cm),
but feel free to experiment.
The frame has two
horizontal support bars for more stability.

The torso height measurement on our packs is the actual distance on the
backpack from the bottom of the padded belt to the top of the shoulder
strap attachment. If you already own a pack that you like the fit of, measure it
directly from the bottom of the belt stitching to the highest point the shoulder
straps are sewn.
Otherwise you can ballpark a measurement on your body using this
Torso Height Measurement graphic.
