Hey, I'm new to this and just had a couple of questions that hopefully someone with experience might be able to help me with. I'm hoping to leave for backpacking in June for the UK, then on to Asia, then to Australia and New Zealand. I'm looking at being gone for up to two years. I've done nine months in Europe already and i just borrowed my brother's pack. I don't know how big it was or the type. I'm looking at buying my own and i've been looking at the Asolo 70L bag. It comes with an attached day pack and toiletry bag. Is that too big, would i be better off with a 60L. I don't know if the daypack and toiletry bag are included in the 70L or if they are additional. Also I'm looking at getting a sleeping bag. Do you think up to 0 degrees Celcius is okay for where i'm going. Which would be better: down or a synthetic. Thanks so much guys, i look forward to hearing from you.
