How do I determine what size (liter) compression sack to get for my sleeping bags?

50 degree mummy bag, 10 liter. 20-40 degree 12-13 liter. 0 degree 15 liter. Those are a rule of thumb, and have worked for me for a while. But not all sleeping bags are that compressible. Sometimes it is trial and error. But if you can get the entire sleeping bag into the compression sack with no room to spare, that's a good fit. If you have room left over, then you're not going to get optimal compression. Just remember, don't store your sleeping bags compressed for an extended period of time.

Description shows 30L bag, photo shows 15L bag - which is correct?

It'll be a 30L bag. It's a generic photo because you're not going to be able to decipher size difference based on a photo.
