In reply to butteredfrog:
I will be gone for 7 weeks. Basically I am planning on carrying as little as possible. Clothes for cold weather, and alpine trousers, one T shirt. 3 pairs of trekking socks, one spare pair of underpants. Didnt want to take a sleeping bag, but may have to. Didnt want to take my MSR either, but wonder if I oughta. Whenever I have done expeditions before, I have taken quite a lot, was hoping to see if I could cope ultra light. Worried I might feel uncomfortable if I skimp too much. Its been a while since I did anything like this. (I'm an old git these days. lol)
However, I am thinking about doing island peak also, which means I will need a rope, axe and crampons. Dont want to carry all that crap with me. Travelling lite is liberating.
