I will be carrying a large amount of Euro notes in Turkey (under the 10k declarable limit).
Since I have a Scottevest Expedition jacket with plenty of pockets, is there any reason to use a money belt?
I don't think the jacket would be any less secure, and if I use a money belt it may look like I have something to hide. I'm flying business class for what it's worth.
the real risk would simply be the money falling out and you loosing it
money belts are discreet, but professional thieves know to look for them (that being said they are a minority)
depending where you are it may or may not be likely you will get robbed, you might be more at risk of being detained by security because you're carrying cash unusually
if the money is just in your bag it's much less likely that if it's on your person because of screening
you would have to take your money belt off to pass security, which is a hassle, but that's how I do it. if it's in your jacket they will probably take the cash out when you pass security, showing the whole world it's there
however when I was in a really bad part of the world I carried cash like a drug mule, by wrapping it inside my inner thigh in glad wrap and tape, or inside my underwear.
one thing I can say for sure though is that if you're bringing cash you ought to wrap it in a zip lock bag with tape and the amount written on it, so if security takes it out they know you will notice if a note "goes missing", turkish security are some of the most corrupt I've ever dealt with
Just keep a regular wallet with not a lot of cash in it so if they take it you won't lose much. I don't know about you guys but when I wear pants and a shirt I don't tuck the shirt into the pants so it actually hangs over the pockets. Makes it a lot more difficult to both see if there's anything in them and put your hand in there.
If you're taking night trains or buses just wear a money belt under your clothes so that if someone tries to jack your shit they won't get to the money. I would also take a lightweight bike lock to lock your backpack when you sleep.
money belts are good because you will always end up taking your jacket off.
You need to wear them against the skin though cos you dont feel the difference easily if its gone otherwise (uncomfortable)
I only did this once and it was much more than 10k for a few days.
this isnt really enough money to be paranoid about, real thieves can get this from a watch in any 5star or suite raid.
Just use the hotel safe way easier
