C . Slide lower backstrap through slots on pack frame and connect turnbuckle to
both ends of lower backstrap. Refer to figure 5. Tighten turnbuckle. This adjustable
lower backstrap keeps the load away from the carrier's back and allows air
circulation between the back and the load. When the turnbuckle is screwed tight,
the strap is almost flat. If the carrier's waist is small, the turnbuckle should be
loosened enough to allow the backstrap to curve in and fit against the lower back.
