Actually that's a very small pack - 30 litres - I know it works with that gear though, because I've carried basically the same.

the second blue pad actually gets hacked in half to make a pad that's cross shaped with the arms of the cross around your butt an love handles in the hammock for warmth.. Both roll up and are carried on the outside of that pack, strapped vertically.

You could of course, spend more, and get a bigger, and heavier, pack at MEC - but I've done up to 5 night
outings with that one.
