I just did a 1 month travel with this bag it's great and much better than their bigger bag. I didn't love the "quick access" pocket location otherwise it's near perfect.
Huckberry had these on 50% sale for a few days awhile ago, I was tempted, cause I like the idea and I prefer lighter bags. But I am already pretty set on travel bags cause I use the 29L Recycled Firefighter 24+ for light (2.4lbs) one bag travel and the bigger Aer Capsule Max for bigger loads. In reality though I am old so if I fly and never need to hike or go down a lot of stairs or cobblestone/dirt roads with all my stuff, I user a roller carry on and personal item lol. If was just starting and didn't already own and use a bunch of packing cubes I'd happily try something like this as my travel bag.
