I was told when I was a nipper in uniform that 'any fool can be uncomfortable'. Not a bad saying and one I have taken to heart throughout my life. So trimming such essentials as sleeping bags without careful consideration is not worth it.

That said, it is fair to say that the army bags that I have seen are very big for their thermal rating and you can get much smaller more modern bags which keep you just as warm.

My recomendation is a duck down bag. down is much lighter and packs smaller when compared to a bag of a similar thermal rating. Couple of things worth thinking about though. One is that down bags don't like getting wet and loose most of their thermal effect when wet unlike artificial fibre which maintains warmth if not comfort when its wet. The second is cost. Down bags are very costly by comparrison.

I use a down bag linked in with a gortex bivvi bag if there is any chance of it getting wet. This combination also gives me the option to sleep under the stars without the tent on good clear nights.

It will be christmas in 9 weeks, so you could always put a bag on the christmas list.

That my ten penneth for what its worth.
