Hi Iain
I did a 4 week trip back in Nov 2006. We climbed pockalde 5800m, island peak 6180 and la boche 6119m.
Like you I was a bit uncertain what mountain clothes to take. I had done a few trips to the alps in summer and climbed in Scotland in the winter.
All our ascents were done in one push up and down from circa 5000m camps in good weather and I found myself wearing my usual Scottish winter gear, so for legs that was mountain trousers with hard shell pants in reserve.
I wore plastic boots for both 6000mm peaks.
I run v hot most folks were using sleeping bags to -15C where I had -5c bag and fleece blanket.
Conditions can change very quickly and on one descent it started to snow and the wind picked up so having an extra layer to throw on is wise.
My advice is to take a range of lite weight clothes that can be layered to cover a wide range of conditions.
Met some folks in katmandu who had frozen their nuts off on mera peak so be prepared.
You'll have a great time, wish I was coming along too!
Cheers Dave
