My 0* bag is much bulkier (packs to 9x17, I bought a compression sack but it hasn't arrived yet) than my 30* summer bag and I'm assuming I'll go through more food and also have bulkier clothing to keep warm.
I was thinking about 65L would be good, but since the Deva is only 60 or 70 liters, go up 5L or go down 5L?
