If going on an rather long trip, going camping and trekking this would mean a tent plus boots whats a good size pack i don't really wanna have to buy all my gear first then get a pack that fits. I've never really camped in colder climates longer than a night or two when snowboarding or hiking and my ex army packs gone to the dogs. Would 70 litres be big enough or to big i'm a budget traveller so will be doing cooking as well but i'll be taking my coke can stove which takes up bugger all room. I'm going to be going from tropical climates to below zero high altitude i won't take crampons or ice picks if need be i'll hirer them i'll probly take a down jacket and layers, as for tent it will be a trap tent so pack extremly small and light weight. also i will be going solo i would rather a smaller pack if practical hate carryin have loads of long periods last time i hitch hiked and i had to carry a lot of gear cause my car had been smashed up and walking 40 km at 3am near killed my carrying over 40kg. any help hear would be good from people who know a bit on the subject never travelled oversea's so any advise is greatly appreciated.
40 kilos = 88 pounds (US, not UK)... that's very heavy.
I and my GF carry a maximum of 30 kilos when we go backpacking 4-5 days in the wilderness. This weight includes (heavy items only) clothes, 2 backpacks, 2-person tent, 2 sleeping bags & full size Thermarest pads, cooking gear, fuel, a bear-resistant canister (to keep paws off our food), dehydrated food for the trip, SLR camera, ceramic water filter & containers and 2-3 liters of water.
With a back-country style pack, I think 60-70L should be fine if you stick with lightweight gear. Better to be a bit bigger than tight size-wise. Make sure the pack can be cinched down tightly. For alpine temperatures, I would buy necessary gears to keep yourself warm and safe before the trip than relying on the host country to have them available. My friends, who relied on an African-based trekking outfit for their sleeping gear, suffered badly on their Kilamanjaro hike.
Thanks for your help,
Yeah i know it was heavy but thats what happens when you have to leave your car behind and you have presents and nick-nacks you've had for years that you can't seem to part with. This atleast instilled in me the imporatantace of packing light as practically possible. I can justify spending money on good gear if it keeps me going, a lot cheaper than a house. i've done a lot of camping and hiking for extended periods but this is generally to a base camp then from there on to overnight hikes. I've been looking into long distance hiking pretty seriously, but i'm hoping not to go any bigger than a 70 litre pack.
I will buy all my gear here because i hopefully plan on doing the Australian Alps Walking Track before i leave this should prepare me quite nicely for anything the future may hold.
I have a 60 litre pack which I lived out of for 5 months in Africa. With the help of solid wood bookends when I left it weighed 28kg - that is heavy (bearing in mind I'm only a small female). I think if you pack sensibly you can easily get away with a 60 - 70 litre pack. Melbourne has some great outdoor stores who will help you out when buying a pack. Fill it with climbing rope and put it on your back to see how it feels. The good looking ones usually don't sit well.
Good luck with the adventure.
