Yes, hoodies are perfectly legal to wear in the airport in 2026, but they are a frequent "trigger" for extra security screening. Because hoodies are loose-fitting and feature large pockets and a hood, they can potentially be used to conceal prohibited items. A supportive peer "security hack": if you are going through a standard TSA checkpoint (not PreCheck), you will almost always be asked to remove your hoodie and place it in a bin, just like a jacket or coat. To avoid the hassle of undressing in line, wear a t-shirt or tank top underneath. If you have TSA PreCheck, you can usually keep a "light" hoodie on, but heavy or oversized ones may still result in a manual pat-down. For the smoothest 2026 travel experience, choose a slim-fitting hoodie without metal eyelets or excessive zippers, as these can set off the metal detector and turn your cozy travel outfit into a logistical headache.
