I have been thinking about making a quilt that zips into a ripstop bottom with a draft tube. Similar to the big agnus bags. That is the best way I can come up with with the least amount of weight. That would make the best multipurpose bag for air/ground use I can think of.
Is that too much to ask? Girls with frikkin' lasers on their heads?
