Very soft and large. Could prob fit a passport in here although not sure you'd want a passport stuck to the front of your bra. For privacy security, do not attach to the front of your bra, unless its on the inside up against your chest otherwise the outline can be seen thru tops. I attach on the side of my bra under where your armpit portion would be and its completely un noticeable. Does not scratch or feel uncomfortable, you will forget its there after about 10 minutes.
