The weight is an issue but at least the straps do help to compress it down to a fairly small size, which is handy as it takes up less room in the bin.
I had one of these at a meet, first time out. I was freezing, thankfully somebody was selling a sleeping bag which i bought and had a better second night. Instead of packing it away i gave the wool blanket to luckylee for some project he had in mind, used the cotton blanket to make some charcloth and cut the zip off the outer (it had broke anyway), sewed it lengthways and now use it as a lightweight bivi bag. It seems to work ok under a tarp as a windproof layer.
