"Overall I am very pleased with the purchase"
I have just used this for 23 nights in Italy.I am just under 6 feet, and have ample room in it. In a refuge, the hood is large enough to fit over a normal sized pillow, and works well. This means there is a lot of material around the head when used in a mummy style sleeping bag, it can work round to block your air supply when you close up the sleeping bag hood, so I didn't close both hoods at the same time. The liner itself does seem to add appreciably to overall warmth. Previous silk liners have sooner or later ripped as a result of my movements, only time will tell with this one, but the material seems to be more robust than that of its predecessors. Overall I am very pleased with the purchase.
