I've been thinking about my earlier statement reference the 511 push pack being a good PSK. It WOULD, but IF is is in addition to, to augment a GHB or BOB, then it wouldn't be all that good as it would be quite difficult to carry with a pack of some kind. SO Like Arch has described several times, a BELT ORDER would be the best way to go. It WOULD be wearable while you have on a pack and you could shed the pack without getting rid of the PSK. NOw to just find a pouch I like the size of and "Get 'er Done"!
