Does my 3 1 1 bag have to be clear?

For the TSA, which regulates travel in the United States, all liquids, gels, and aerosols must be in containers that are 3.4 ounces (100 milliliters) or less. All liquids must fit into a single, clear quart-size bag — passengers can only pack one of these bags in their carry-on.



Yes, per TSA regulations that remain strictly enforced in 2026, your 3-1-1 liquids bag must be clear. The "3-1-1" stands for 3.4oz (100ml) containers, 1 quart-sized bag, and 1 bag per traveler. The bag must be transparent so that security officers can quickly visually inspect the contents without having to open it. While many travelers use a standard Ziploc-style bag, you can also purchase more durable, reusable clear TPU or PVC bags as long as they meet the quart-size volume limit (approximately 7 x 8 inches). If you use an opaque or mesh bag, you will likely be stopped and asked to transfer your liquids into a clear plastic bag provided by the airport, which can cause delays at the security checkpoint.
