Not cheap, but I use Hill People for a couple different purposes. One being their chest pack when I hike or ride my bike. SubCompact, blade, and ID fit no problem.
We love to put things in ALICE...still have one.A high-volume ruck? A 3-day ruck?
I have a love/hate thing about the ALICE, but the large ALICE is one of my faves. I'd love to own another.
Mystery Ranch, Tactical Tailor, LBT, Gregory (the UM-21 patrol pack is my fave small-volume 3-day pack).
