The rig I’ve posted previously can be worn with 4-point harnesses, using simple waist strap on the 5th and 6th points for more stabilization.
But these points can be utilized also as attachment points for pouches (and perhaps even gunbelts or warbelts, not tested it yet).
Compact chest rigs that integrate into the backpack’s straps are not new – D3CR+FlatPack from HSP (read – VOCR from EGL), Ventrapack from CivilianLab, to name a few. I’ve always wondered how pricey they are, noticing the small dimensions and overall amount of labor put into them.
Now, let’s make one for the price of pouches, set of Chinese-made rectangle carabiners and pair of soft snap-button PALs attachment clips.
