Although to the credit of kelty, REI, MEC and a few others, there are a few midrange lighter weight down bags which offer at least some sort of middle ground. it wasn't that long ago it seemed to me that it was either something in the price, weight and quality of the WM bags (which is very good) or really really heavy and bulky. Yes, those kelty and REI bags are not as light as a WM bag, but they are not *that* heavy either. It used to be a lot more difficult to get a lighter weight bag.
