Thread: What size back packs do you use?

15 litre day pack with 2 litre water bladder when hunting from a base like a road end camp (easily fits in the chest cavity on a whole carcass carry out). 30 litre pack (enough for the hennessey, a bag and some tucker) with a 3 litre bladder if I am doing 1 or 2 nights in. And a beast of a 100 litre if I am going in for a stretch (as in the roar).

The problem with the bigger pack is I always end up carrying stuff that I don't use (although I wouldn't leave the first aid kit behind as you never know when it will be needed).
