Bought this in green as I am not military but shoot regularly. The whole package is really easily modified and is fully modular. I have tried it as a waist pack and a chest rig at the range. Waist pack is less alarming to the more sensitive club members, but full chest rig is so stable and quick to reload. I also plan to use it on the hills as I take groups out in the wilderness and having vital supplies to hand could be very useful. Just one note, the extra duty costs for UK buyers was a nasty shock, despite knowing there would be some. I have now registered with Carcajou as a veteran and so should get some discount going forward.
