The locking hooks are practical, the bag can be mounted very quickly and safely. However you have to watch something that really hooks engage audibly, or they will at some point and that is exactly what you do not want. But if they are engaged can not happen really, the straps are also very stable.
The comfort in the leg (I wear them on the lower leg) is very good, sometimes I grab my leg because I'm not quite sure if the bag is still there ;-)
Even in the tropics, you can carry the bag without you sweat in addition.
A passport fits of size purely good, but you have to accept the fact that he takes the time some bending, according to the shape of the lower leg.
Banknotes are also good, some, however, give very little, sure, there are bills that are too long, but I have no encounters.
