I've used this bag down to about 20 degrees and it was true to its rating when you shift most of the down to the top of the bag. The zipper hardly snags and there is minimal…

Sometimes, they listen to some pretty different music in the office. Now is one of those times, so if this isn't very helpful, it's because I'm super distracted by some kind of 8-bit 80's video game music. They guy who sits across from me put it on. I'm totally just going to glare at him for the rest of the day. Plus, Twitter is down, so I might as well write this stuff about sleeping bags.
First thing's first: you gotta pick a bag to match up to the temperatures you're expecting to sleep in. The temperature rating for most sleeping bags are pretty much just guidelines. So, for a bag rated at 30 degrees, that 30 degrees is the ideal usage. Your sleeping pad, baselayers, and just your general body coldness are going to definitely have an affect on how well a bag works for you.
If you need a little guidance in the choosing a sleeping bag department, check out something they use across the pond called the EN Test. That means European Norm not Egyptian Nursery. The EN Rating has three levels: the Comfort Limit is based on a standard woman having a comfortable night's sleep; the Lower Limit is based on a standard man at the lowest temperature to have a comfortable night's sleep; the Extreme Rating is survival rating for a standard woman. Try to avoid that one, you guys.
Marmot and Mountain Hardwear have adopted the EN Rating in the United States. Keep in mind that sleeping bag manufacturers may vary quite a bit. So a 15 degree sleeping bag from The North Face may not let you sleep as warm as a 15 degree bag from Marmot. It just all depends on how conservative that manufacturer's rating system is. Most test ratings also assume that you're really snuggled in, with the hood cinched tight and neck baffle sealed (if the bag has one), so you'll want to keep that in mind when you choose a sleeping bag.
The ratings for most sleeping bags is going to be around the Lower Limit of the EN Test, so if you sleep cold, you might get a bag with a lower temperature rating that what you're expecting. So, if you're expecting 15 to 25 degree nights, and sleep a little cold, you might be best off choosing a 0 degree bag instead of a 15 degree bag.
Aside from temperature rating, filling material is another factor to consider. Are you going to get down or synthetic? They've both got their strengths and weaknesses. Down is lighter and more compressible, but if it gets wet, you're done. Synthetic sleeping bags are a little heavier and less packable, but they retain their thermal efficiency when wet. I learned that phrase, "thermal efficiency", from an scientist. I'm not sure I'm using it right. I usually only use it at the coffee shop to explain how I want my latte.
Twitter's back up now, so I'm going to cut this short. Check out this indispensible info on our sleeping bag buying guide that I wrote.
