Backpack, canoe or pulk. What I pack mostly depends on season. Tarp, groundsheet, reindeer hide, sleeping bag or blanket, cookpot, kåsa+spoon, often the firebox, clothes (not much, wool pants, dito undershirt, wool shirt/buckskin shirt, hat, bandana, perhaps a sweather, etc), axe, perhaps saw. Food. Knife, cordage, etc.
Might carry stuff like reflector oven or skillet if canoeing with the familly, else it stays home. Fishing gear quite often. First aid kit always.
Stays fairly ok in weight, winter clothes add a bit, so does food for longer trips.
I have done summer trips with minimal clothes, blanket, cookpot, knife, axe, poncho and food, and it is very nice, but the SO will not play at that level, and the kids need a few more years to ease them in. By the time they are 10 or 12 I'd guess...
