I recently ordered this pack and the 5.11 Rapid Origin Quad Zip as I wanted to compare and see which pack I preferred. The AMP24 is a great pack, I found it very comfortable to wear and the build quality is excellent, although the small pockets on the front are hard to access. I ended up keeping the Quad Zip pack as I prefer the shape of that pack and it better suited my needs. TacSource have been a pleasure to deal with and the return process was very simple.
