🏊 Wetsuit

A wetsuit is clothing and has no security restrictions — screeners will not confiscate it. The only issue is size: a thick full-length wetsuit rolled up can be too bulky to fit in the overhead bin, in which case the gate agent may ask you to gate-check your bag. Security itself will wave it through without concern.

Wetsuits face no restrictions in the US, UK, EU, Canada, Australia, or any other major aviation system — they're classified as clothing with no prohibited content. The treatment at checkpoints is the same everywhere: the wetsuit goes through the X-ray with the rest of your bag, and that's the end of it.

A thick rolled wetsuit can look dense and opaque on the X-ray, occasionally prompting a secondary bag check to confirm nothing is hidden inside. Screeners may physically unroll it or probe it to get a clearer image. It's not common, but being cooperative and patient if it happens will resolve the inspection quickly.

For shorter trips where a 3mm or thinner wetsuit compresses to a manageable size, carry-on is fine — just ensure it fits within your airline's overhead bin dimensions. Thick 5mm or 7mm full-length suits are much bulkier and are better suited for checked baggage. Roll the wetsuit rather than folding it to minimize crease damage and save space in your bag.
