Hi Greg,
I don’t think your problem is your sleeping bag. From what I remember from Physics.. sleeping on an air mattress in zero temperatures is the equivalent to sleeping on a block of ice. It has to do with getting rid of the air and the ability to heat your surrounds with body temperature. If you can get rid of the air, you can actually sleep in packed snow (which is ice) and stay warm. The worst thing in the cold is air mattresses and the old hammock type beds. I remember doing the same clothing up in Kinglake once in July school holidays. Worst night of my life.
Tony’s sons on to it, even if you just have the swag without the heater.. though that would be nice! Swags are great if you don’t mind carrying them around. Not so great for hikes though!
If all else fails, get a good wetsuit and pee in it. It works in the surf!

Gooday all
While birding at Round Hill NR recently I learnt two things. One, when crashing through and climbing under and over the endless thick mallee scrub with bruised shins, scratched face and collar scooping up endless handfuls of sticks into my shirt, just stop, back off and follow the wife, she always finds the easy way. Two, never ever believe a two hundred dollar sleeping bag rated at so-called -7 degrees will keep you warm even if you wear thick socks, long undies, trousers, T shirt, flanelette shirt, two jumpers, a scarf, beanie and wool gloves in the bag at the same time. We also had air matresses and extra blankets and quilts.
So, can someone please suggest a not too expensive but warm sleeping bag when temperatures are about and just below zero, or, how do others go about keeping warm in such conditions.
Thanks
Greg Little
