Mike O.wrote a review of Western Mountaineering MegaLite Sleeping Bag: 30 Degree Down on June 5, 2012
Received mine last week and took off for two nights. It was 38f and damp as is usual in the Sierras this time of year. I was totally warm and dry.
I have a MontBell 32f that cost $40 less and I was freezing last month. Big deal..save $40 for Chinese junk. I also had another high end brand 32f bag...same thing..Chinese junk.
I also have an Alpinlite. It is too much unless around or below 32f. WM bags are the only ones with real temp ratings.
