Why Does My Crotch Set Off Airport Security?: 1 Minute to Understand Airport Security Scans and Common Triggers

It can be both confusing and embarrassing when your crotch area sets off airport security alarms. Generally, airport scanners are designed to detect foreign objects or substances, including metals, dense fabrics, or anomalies in your clothing. The crotch is a typical “hotspot” because it’s a location where people may try to conceal items, prompting extra scrutiny from security technologies like millimeter-wave scanners and metal detectors.

Some common, legitimate reasons your crotch might trigger an alert include: metallic elements in clothing (such as buttons, zippers, or decorative fabric), medical implants, incontinence pads, menstrual products, or even sweat causing an unusual reflection in the scanner. At times, thick seams or layered fabric could appear suspicious to the scanner software.

From a designer’s perspective, I always advise clients to consider garment construction and fabric choice—especially while traveling. Opt for airport-friendly outfits with minimal hardware and avoid bulky pockets or extra padding in sensitive zones, which can also help streamline your security experience.

Tips 1:

If you have a medical device or wearable, always carry documentation and notify TSA agents in advance. Also, keep your outfits simple and check the labels for hidden metal pieces before heading to the airport.
