I used to have a snugpak elite 5 it was very warm but very bulky and very heavy.Sapper did you have a softie 9 Hawk?, been searching around for light bags now i've seen this I bloddy want one!
The mountainlife everest is not that much different in price but is a lot lighter and unbelieveably smaller.As a comparison my kids have karrimor 2/3 season synthetic bags weighing 1.1kg, the everest is heavier but packs down almost as small.
