With just a backpack, it is already nightmare through security. I can't imagine walking back and forth fishing out that one last thing over and over from all the nooks and crannies.
you can just take off the vest and put it through the x-ray in most airports i think?
Yeah, security is a complete non-issue here (assuming you still follow the carry-on contents rule)
No laptop in it's own bin, some countries need you to put phones, battery packs and other electronics in separate bin etc. Wish they made the process easier.
