Teach me about light weight sleeping bags

[northumbrian]

ive just got an army one which weighs a ton but is bombproof but ive also got THE SLEEPING BAG from snugpack which is 1700 grams is comfort to -2 and the low is -7
and it cost just £23 worth a pop at that price ?

northumbrian - remember that this is what Snugpak rates the bag at. A quick look around the net confirms what I found out about my own Osprey - nice bag, but the temps. tend to be optimistic.

well it should be at least a 3 season bag then ? i can imagine the size of backpack i will need to carry that one and the uk army one as a back up when i try it out in the cold.lol
