With some romantic tacti-coolness in mind, this concept was born. Two compartments with independent entrances.
Second prototype photos is available in previous post – entrance prototype.
Pack is easily reconfigurable from two cells to one cell, with un-buttoning of internal divider.
Note important detail – straps to be attached in different points then configured in two-cell (dark green triangle) and one-cell (bright red triangle) sets. The reason is – then in two-cell set is loaded only upper compartment, and straps are attached with lower point, pack tends to collapse.
