Great 'flight pack'
I intend to mainly use this bag as a flight pack hence the title. I find it is the perfect size - small enough to comply with airline 'under-seat' size requirements yet large enough to hold my 12.9 inch iPad or even my 14 inch MacBook. It is very well made, has good security features and it is comfortable when fully loaded even without the shoulder pad, which I am not keen on as I think the velcro tabs sticking out make it look a little tatty. The shoulder pad also moves along the strap easily so is rarely in the right place. However the strap is wide and comfortable so I don't find that the pad is required.
The pockets are a good size and I can fit in everything for a flight (iPad, hardback book, power bank, phone, passport, wallet, water bottle, etc). All in all this is a great bag which would be perfect for me if: strap was fully removable, zip pulls didn't jingle quite so much and more colour ways were available (Navy Blue would have been my first choice).
