A very large expedition-grade backpack which will hold 2-3 pro DSLRs with grip (one with up to 600mm f/4 lens attached), 5-7 additional lenses, 2 flash units, tripod or monopod, accessories and personal gear and a 15.4” widescreen laptop. The ActivLift harness follows the curve of the spine, transferring more weight from waist to hips. It also has improved airflow, and can be adjusted to suit different torso lengths. The backpack lid, which takes clothing and personal items and has multiple pockets, can be removed and worn as a waist pack. With tripod holder, hydration pack pocket, multiple accessory pockets and attachment points for additional equipment, it is the complete solution for the trekking photographer with a lot of gear.
