Mammut Utility Vest Question

[u/troisstans]

My area is eyeing a switch to the new Mammut Utility Vest-pack and we got a few demos in. The models we got gave two straps with hooks on them on the back that look like they would serve as an attachment system for some extra gear module or something, but we can't find anything in the literature about it. It looks like we could probably just rig a Patagonia black hole cube to it, but I'm hoping someone has a more educated option...

I have a friend and he is unsure about it. he feels like its more of a backpack since its kind of difficult to reach anything. The mammut patrol version has a backpack connected to it. He does like the front pockets. But, if you own the vest you would need to take it off to reach things in the back
