Does anyone have both a ULA pack (hip belt) and an Atom Packs pack? I contacted Atom Packs and they say the slot for their hip belt is the same configuration as I see on the ULA pack I have (4.5 inches wide with velcro (scratchy and fuzzy) sides facing the same. I want fully integrated, sewn-in hip belt pockets and Atom Packs won’t do that (they only offer removable). So, if you have both…will your ULA hip belt go into the Atom Pack slot and work well? If it matters, I’m interested in getting the Atom Packs Mo.
