>Do you know any good brand ?milsurp. Specifically, the US Alice pack. if you're just after the frame, the Sturm reproduction is also acceptable, but their bag is of lesser quality. Also, most of the surplus ones and all of the reproductions lack the bottom shelf, so you might have to get that as an additional part (or just bend and drill a bit of sheetmetal into the right shape).
