The one piece of clothing TSA says to avoid wearing at airports during holiday travel |

Holiday travel is already stressful. But the Transportation Security Administration(TSA) says what you wear can make the experience even harder. As travelers flood airports during the festive season, the TSA has issued a reminder about one specific clothing item it recommends avoiding at security checkpoints.In a Dec. 18 Facebook post, the agency cautioned passengers against wearing sparkly outfits, especially festive sweaters that are common this time of year.“TSA PSA: The body scanners don’t love sparkles. We don’t want to dull your holiday shine but we don’t recommend wearing your sparkly holiday sweater to the airport,” the agency wrote.

Why sweaters and bulky layers can slow you down

Beyond sparkles, the TSA says certain clothing items may need to be removed during screening. What the agency defines as light outer garments or bulky clothing often triggers additional checks.These items include windbreakers, vests, light jackets, pullover hoodies, large sweaters, cardigans, and ponchos. Removing them helps officers get a clearer image during the screening process and can speed things up for everyone in line.According to the TSA, belts, clothes, and shoes are generally allowed in both carry-on and checked baggage.“To help TSA officers get a clear look at your bag and reduce the need for additional screening, we suggest you pack your bag in neat layers,” the TSA states on its official website.The agency maintains a detailed list of items that are allowed or prohibited, which travelers are encouraged to check before heading to the airport.

Clothing and accessories you can pack or carry on

The TSA says the following items can be placed in carry-on bags or checked luggage:Bobby pinsBoxing glovesHand warmersHandcuffsHeadphonesHelmetsNight vision gogglesShock collarsShoe insertsSkates, including ice skates and rollerbladesSports cleatsSteel toe bootsWallet chainsSome items come with specific guidance. For example, body armor is permitted, but with a caveat.“Generally, body armor is allowed in carry-on or checked bags,” the TSA says. “Please note however that even if an item is generally allowed, our officers make the final decision on whether an item is allowed through the checkpoint.”For heated jackets or sweaters, the TSA advises travelers to follow Federal Aviation Administration regulations related to batteries.When it comes to jewelry, the agency offers a safety reminder: “If you are traveling with valuable items such as jewelry, please keep those items with you at all times (do not put them in checked baggage).” The TSA adds, “You can ask the TSA officer to screen you and your valuables in private to maintain your security.”Life vests are also allowed under certain conditions. “You may bring a life vest with up to two CO2 cartridges inside, plus two spare cartridges in your carry-on or checked bag,” the TSA says. “You may not transport CO2 cartridges without the associated lifejacket.”

Items that are restricted or require extra caution

Brass knuckles are not allowed in carry-on bags but can be placed in checked luggage. Even then, legality can vary by state.“Although these items can be placed in your checked baggage, they are still illegal in some states,” the TSA writes. “Should the bag need to be opened for some reason and there is an illegal item in the bag, TSA will be required to report it to local law enforcement.”
