Craig,
Just wondering what you had under you to sleep on.
I had my Summerlite out last weekend too. (Mt Samaria out the back of Mansfield) No problems for me, and I was in just my softshell jacket and pants with a midweight thermal top. I used an Exped Downmat 7 for the first time. More comfortable than my IAC and MUCH warmer. Sleeping in the 'mid with the two kids.
I'll take this combination up Bogong next weekend and let you know how it goes.
I have slept on snow before in my belay jacket in the Summerlite. A bit cold on the IAC, but plenty of room. It is a bag for skinny blokes.
