As stated this harness is designed to work with the entire Esstac Boar line
of chest rigs. It is particularly useful on the bush boar A1. With the standard shoulder straps you find yourself having to organize the shoulder straps, and hold them in place to get into the rig easily. With the padded harness it's just like putting on a jacket; one arm at a time. SUPER EASY. Not only does it make for mounting the rig easier, it makes carrying the load much more comfortable, not that the Esstac Boar line
was uncomfortable to begin with, it just makes it that much more pleasureable. IMO, this is a must have addition to this line of chest rigs. It would be interesting to see how this style, when made to integrate properly, would work with other rigs.
