Best low profile Backpack / 48ci HPA tank mounting method

[Digital]

Up until now I was using british webbing; wanting to save for a proper plate carrier instead of £20 amazon one. However, until i do eventually get a plate carrier, I would like to run a battle belt. I don't want to mount my 48ci HPA tank to the battle belt, due to badly distributed weight, limited space and my current electronic prototype system which needs its space (more on that later...)

So; i need a backpack. It needs to be stupidly slim and low profile, so i don't look like a camel when prone (I often use dmrs)

Any ideas?

Not looking to spend much; all help is appreciated! Thanks!

P.s I use a mancraft reg if that helps (quite tall)
