Here's what to check for when choosing a sleeping bag:
Fill is either down or synthetic, and both have their advantages. Down fill is loftier, warmer for its weight and comfortable over a wider temperature range, but synthetic fill dries faster and still insulates if wet.
Narrow sleeping bags are warmer however they are a tighter fit and will restrict movement more. A hood is needed for winter, and a circular or oval cut at the foot won't compress the down (making it warmer). Getting the length right will also minimise spots for cold air. Sometimes a shoulder baffle is useful too.
There are generally four accepted temperature ratings for sleeping bags (Upper Limit, Comfort, Lower Limit and Extreme) although not all companies use them. The Comfort level is a good indicator, but use your experience in a summer sleeping bag to judge how you sleep (hot or cold). These ratings are only a guide.
