i saw something like this at cathay.
if i didn't rem wrongly, it is S$147 domke medium size. fits well.
i also read this review.
however, unlike a DSLR or a professional camera bag, a vest really makes a big difference to your appearance. i just wonder what would it be like when you wear this vest, walking in singapore or walking overseas? the possibilities is infinite. rather than leave to imagination, i'm just curious if there is anyone here, not being a reporter or photographer by profession, who wears such vest - and what is your experience with people who saw you with such a vest?
