G'day Cliff.
I carry two military waterbottles with two cups canteen in their webbing pouches.
My PSK as you yanks call it is part of my belt kit I wear when out bush. I wear old military webbing with 2water bottle pouches and three minimi sized ammo pouches for my other gear. Very handy when I used to go shooting in the Northern Territory or now as I don't shoot anymore (tough gun laws) just for bushwalking and camping.
Love roughing it and don't need half the stuff some people here seem to carry.
As I kid all I ever used out bush was a box of matches a pocket knife, pocket full of string, a tarp and an army water bottle on a webbing belt. Oh and some tucker to eat.
