I recently bought an Osprey Ariel 60 for my thru-hike next year. The small is at 3800ci. I have some 2-3 day experience (used my Atmos 50) but none for longer hikes. I'm afraid that 3800 ci will be too small and am thinking about upgrading it to an Ariel 70, which at a small will be 4400ci. Is that needed or will I be okay with 38000ci?
I should mention that my hiking style is not minimalist but not overloader- just comfortable.
I am also going SOBO so my concern is starting with the 100 mile wilderness with not enough room for 8-10 days worth of food plus winter gear in a 38000ci. Thoughts?
