John,
I guess it depends on what you mean by a few items. I put my compass and map in a eagle creek passport/cash neck pouch sometimes. I also have 2 HPG kit bags that I love. But it’s easy to overload any bag or pack.
I notice you didn’t say lightweight. Some people on the bushcraftusa forum are going with a condor T&T pouch combined with a chest harness made by primaloutdoors for alot less money. The condor does have D rings and is cheap(probably heavy too) that look like you could connect to shoulder straps with out the harness.

There’s another one too, if I find it I’ll post it. I always wanted to find someone to sew a similar Kit bag mesh back part and connect it to the zpacks multi-pack. It could be done real easy and you can get extra straps from zpacks. Then you’d have a light weight option.
