We have used the ScottyVest line for travel with great success. Many items have up to 23 pockets in their outerwear jackets that can carry as much as a carryon.
There are no airline restrictions on jackets etc that I know of.
Nope, you aren’t missing anything. We in an Apex SV ( just leaving Amsterdam too) and that is our room as set up as well. Love the extra space and especially the lounge chairs on the balcony.
