What RFID blocking does, what concealed pulls and pocket placement add, and what costs nothing.
Most of what a bag can do against theft comes down to where it keeps your valuables, not to a feature on the label.
RFID blocking costs little and does little. Card skimming in crowds is rare, and modern cards carry their own protection. Don't pay extra for it or choose a bag on it. Having it is not a fault. For what else is sold as anti-theft, see anti-theft theater.
Three features do more. A concealed zipper pull lies flat against the fabric, so the bag is harder to open without you noticing. Back panel access means the compartment only opens once the bag is off your back. Pocket positioning matters too: valuables in exterior pockets facing away from your body are within a stranger's reach, and valuables in interior or back-panel pockets are not. Hidden pockets covers where each kind sits and what you can reach while wearing the bag.
Where valuables sit, keeping the bag in front of you in crowds, and not leaving it unattended cost nothing. A feature adds to those habits and does not stand in for them. The best anti-theft bag used carelessly is less secure than an ordinary bag used with attention.
For a concealed zipper pull, close the zipper and run your fingers along it. The pull should tuck under a flap or into a fabric garage, so you have to lift it out before you can grip it. For an RFID claim, look inside the pocket for the blocking layer, usually a silver or grey metallic lining, and check whether it covers every wall or just one. For back panel access, put the bag on both shoulders and reach back for the zipper. You shouldn't reach it. Then slip one strap off and swing the bag to your side. If the panel opens from there, it needs the bag rotated, not removed. For pocket positioning, list where your passport, wallet and phone ride and ask who could reach each one while you wear the bag. The answer should be no one.
In low-theft places, most anti-theft features are cost and complexity for little return. For bags used only in offices, schools or familiar neighborhoods, they add little. The case for them is stronger when you travel abroad through dense tourist areas.
