A Western Mountaineering bag (Alpenlite) comparable to the Kelty (20F) is more than a pound lighter, has less fill, but uses 850 down and costs $480. WM also has another 20F bag the Ultralite that is narrower and costs $435. In other words for 4 times the cost, you get what many consider the best. Proves my point-light, warm, cheap-pick two.
