I have the Montbell Permafrost Down from a few years back. Will the Frost Line sit closer to he body...less of the 'Michelin Man' effect?
Trying to decide between this and the Mavericks 30. Will use only for summer camping. 3-4 nights at a time. Nor Cal (Napa, Calistoga, etc.) weather. Seems like the 30 would be more versatile for the mountains, but could be too warm otherwise?
