Debating between the 27l and the 35l. Are they really closely the same in terms of form factor? Don't want the 35L to hit people behind me when i'm turning around boarding a plane or to work everyday. 35l space is ideal for me to fit under the seat too on the airplane but i'm debating the size man! Price of 35l is like few bucks more too...
You used the wrong strap for compression straps. The one you attached was the sternum strap for the shoulder straps. Both the 27 and 35 have pass through access. Interesting the 35 is same height as 27. Thank you at the attempt.
