Updated for 2015, the Classic Down series offer warmth, compressibility and the Big Agnes System bag design. The Storm King +0 combines a roomier contour shape with a narrower pad sleeve to provide an overall more comfortable and cozier sleeping experience than ever before. BA also redesigned the bag to be taller across the top so you can roll over more freely (side sleepers rejoice!).

For sizing info - I'm 6'3 or 6'4 and the long version allows me just enough room to side-sleep with my arm under the pillow supporting my head and my legs not-quite straight. That's how I sleep at home, and this bag allows me to sleep the same way on the mountain. No major sleeping changes required.
You can go lighter for sure, but you're spending a LOT more money to do it with an 800-850 fill down bag. For instance, BA's new "Pomer Hoit" 2015 0 degree bag uses better 850 fill down - you'll spend about $600 on it, and it'll save you about a half pound.
The pad is important - you need to get an insulated Big Agnes pad (or an even better R-value pad from other manufacturers) to max out the temperature rating. I have the insulated Q core SL and it's perfect with this bag. Good combo.
I've used the bag:
1) in the open, without a tent in 20-degree temps and slept nice and warm. Waking up to a frost-covered bag while you're still toasty inside is amusing. Plus you look kinda tough at a campground sleeping 'under the stars' in sub-freezing temps...
2) with a floorless pyramid tarp at 9.000 feet up on Mt Shasta on a windy night in January (on a warm weekend for January) and just tossed this setup into a trench a dug in the snow and still slept warm enough. On a cold night, on a cold surface, plan on putting more air into the pad as the air inside cools and the pad sinks (after maybe 30-45 minutes) - the more space between you and the ground/snow, the more warmth can be retained.
3) in warmer temps too. Leaving it unzipped allows a you to bleed off enough body heat in cool temps to stay cozy. I'd never use it in summer, but you're still good into the 40's (maybe 50's?).
AS WITH ALL BAGS - the temperature rating is the "you won't die" rating, and not the "you'll be comfortable" rating. Don't take ANY 0 degree bag out on an actual 0 degree night and wonder why you were shivering cold that night. Consider all 0 degree bags to be ~10-15 degree bags (depending on you, and your base layer), and then you're on the right track.
That being said, you'll be hard pressed to find a better balance of comfort, warmth, and price if you need a winter bag.
BA Lost Ranger with this bag, well pleased.
I think the warmth rating of bags has no real value. I'd love to see a bag that you would actually stay warm at zreo degrees.
Overall I'm happy with this bag but because of the price had hoped for more obvious warmth difference than my cheap $30 bag.
