I had a Snugpak softie Hawk 9 (or whatever it was), and generally thought it was crap. Too small (I am 6' 3" and 16stone), and not particularly warm for its pack size, while at the same time being horribly clammy and sweaty in warm weather. The insulation starting breaking down - you could tell, it lost most of its loft and it got progressively less warm. My son took it on his world travels and binned it somewhere in Asia as he also thought it was rubbish. I suppose on the upside it was reasonably well made (apart form the insulation breaking up) and after a few years of abuse still washed up well.
I went to down bags after this one and they are waaaaay better. Lighter, small pack size for warmth, and much better drape over you while sleeping which means warmer and more comfortable to be in. The comfort range extends both up and down the scale more than equivalent synthetic bags. If you can afford one get a roomy down bag. It will last for years and you won't regret it.
If someone says synthetic bags are better when wet, yeah right, like you are going to have a decent nights sleep in a wet bag whatever it is filled with.
