I purchased this thinking it would be a smaller pouch, but it's actually huge (my mistake for not reading the dimensions). I CANNOT see how this pouch could be discreet on anyone. I mean I could have fit a book in this thing and had room to spare. Definitely not something I could comfortably wear on long backpacking trek through Europe without worrying about becoming a target, because it would be so obviously visible under anyone's shirt. Sent it back without any fuss so that was nice.
