AER Go Pack vs Chrome Volcan Pack

These are going to be more suitable for ‘true’ one bagging (ie when you travel without a checked bag). If you decide to opt against a checked bag, perhaps look at a packable day bag and one of your options above, or take a look at the Peak Design Travel Bag, as this is designed with photographers in mind, is effectively a big bucket of a bag, and can expand from 35-45l (although I think when expanded to the full 45l it is slightly too big for most airlines). For a daily carry, you ideally want to be looking at something 25l or less, even under 20l.

This is a personal preference, but I do also like that it isn't too strappy. Don't get me wrong, a hiking bag is great but when you're running around the store, office, airport, wherever, all those straps become flails that hit everyone, or catch on everything. The only thing this bag has is a chest strap, which is just about perfect for an everyday bag. The cons: This bag is big
