Packing up my gear so I can ship it up for an upcoming hunt. Flying in with 70 North and floating the Ivishak on the 29th. Debating between my North Face Aleutian 4s (0 Degree) and the 3s (20 Degree). I contemplated buying a new bag for the trip, but I already have 3 sleeping bags, so I am going to make one of these work. The 3s stuffs nicely into a compression sack and is much smaller in terms of packed size. I have used the 20 degree bag here in temperatures down to about 18 degrees and was really quite comfortable. I am leaning towards taking the 20 degree bag. Thoughts on whether its necessary to bring the 0 degree instead, despite its much larger packed size.
Thanks in advance.
