Oh right, that's more of an alpen rucksack than a veshmeshok, i think. Cool yeah, but the strap/loop design is sort of iconic. I washed my unissued one to get the stores-stench out of it and the colour bled out more than i expected, but it looks so cool now. I'll get some pics together sometime and put them in the Loadout Pics thread.
Yeah, if i've understood your diagrams, and fair fcuks to you for info presentation skills btw, i use it pretty much the same, except i do the button up - it's just bloody annoying compared to a canteen that goes in a pouch which stays attached to the belt. I don't trust it to stay on my belt when i run without the button done up, but i need to figure out some way of stopping it bouncing about like a tit fantasy anyway. I wish i could understand Russian so i could take part in discussions on Russian ex-service forums, because they must have found a way to stop their personal supply of tank anti-freeze from being such a ball ache!
